For our second interval act, we have local Austrian hero DJ Parov Stelar.
Known for his electro-swing style, he’s premiering a brand new song, called Black Lilies.

We've seen them all. The votes are pouring in. It's time to stretch my legs.
Eurovision organisers aren't daft - and they know viewing figures go up throughout the contest, so they kept some of the best songs for the second half.
The romantic Italodisco of Sal Da Vinci got the best reception in the media centre, even triggering a conga line at one point.
Presumed favourites Pete Parkkonen and Linda Lampenius were also immensely popular. Linda played her violin so passionately that half the horse hairs on her bow snapped off.
The bubblegum rock of Jonas Lovv's Ya Ya Ya was a proper guilty pleasure, and British-Cypriot singer Antigoni gave her best performance of the competition, sashaying her way around the arena.
I have a feeling that everyone's predictions are up in the air after the last two hours.
The competition seems wide open - but we'll see who slipped up and who rose like a phoenix soon enough.

Voting is still open for about half an hour or so.
Here's a reminder of how it works:
Each country gives two sets of points:The first set is awarded by a jury of seven music industry professionals, while the other comes from viewers at home.
How to vote: Viewers from participating countries can vote by telephone, SMS, through the official app and at ESC Vote, external.
Do I have to pay?: This year you have to pay to vote, either using a credit card or Apple/Google Pay. In the UK it's 15p per vote. Elsewhere, it costs up to €0.99. As well as aiming to raise money, it's to help stop fraudulent voting by making sure votes are coming from the country they are registered in.
Can I vote for my own country?: No, afraid not.
How can I find out how my country voted? Once the voting window has closed, the spokesperson for all participating countries will reveal their jury points live on air.
What happens with viewers' points?: Viewers' points from all participating countries are added up following the jury points, and revealed from the lowest to the highest.
The result: This leads to the nail-biting result, which will reveal the winner of the 70th Eurovision Song Contest.

In celebration of Eurovision’s platinum jubilee, we’re about to hear an all-star megamix of the contest’s most memorable songs.
There are 1,789 to choose from and, while I don’t want to spoil any surprises, they’ll probably end with Abba’s Waterloo.
To guide us through 70 years of music, we’re joined by former contestants including former winners Alexander Rybak (2009), Lordi (2006) and Ruslana (2004).
Keep an eye out for Miriana Conte bouncing on her medicine ball, Lordi’s tribute to Brotherhood of Man; and a hoedown version of Cliff Richard’s Congratulations.

Hats off (or should that be boxes?) to Jonathan and his friends for their attention to detail.
They've taken their Eurovision costume inspiration from Look Mum No Computer.
"Come on UK!!!! Enjoy the party watching Eurovision," he says.

Image source, Getty ImagesPhew, we did it - we got through all 25 performances!
We've had opera, dance bangers and everything between.
There is often quite a bit of chit-chat now with the hosts backstage. Then each country's jury votes are revealed in turn.
Graham will guide us through the leaderboard as the points tot up. It gets tense!
The points are dished out from the public from each competing nation and then announced one by one, starting from the bottom of the scoreboard. The points are added up very quickly and the result is then announced!
The winner is handed the microphone-shaped trophy and they get to perform their song one more time.
And, breathe.
What a ride! We've just blasted through 25 songs in quick succession, from pop to EDM and heavy metal.
It's been energetic, and competitive, to say the least.
Voting remains open for now, so make sure to cast your ballot, and we'll continue to bring updates right here - stick with us.

Image source, Getty ImagesJJ won last year with Wasted Love
This year's host country has taken part at Eurovision 57 times, and has won it three times - firstly in 1966, with Udo Jürgens' ballad Merci, Chérie.
Austria's second win was in 2014, with drag artist Conchita Wurst singing operatic pop ballad Rise Like A Phoenix; while last year JJ, a counter-tenor at the Vienna State Opera, sailed to the top of the leaderboard with electro-ballad Wasted Love.
However, as this year's contest hosts Victoria Swarovski and Michael Ostrowski pointed out in Tuesday's semi-final, Austria has also had its share of being at the bottom of the leaderboard (along with Norway and Switzerland).
The three of them have received nul points four times - the most out of all the other competitors. Finland, Germany and Spain are just behind, having received nul points three times.
Unfortunately for Austria, one of the moments when it received nul points was when it was hosting in 2015, so they will of course be hoping that won't be repeated tonight.

Image source, Getty ImagesCósmo – whose stage name "reflects his fascination with the universe" - is up now, representing host country Austria.
His song is concerned with more earthly affairs, taking a bureaucratic approach to nightclub culture. Cósmo, you see, is in charge of dance licences, and he’s policing the dancefloor with a beady eye.
I’m sure there’s a deeper meaning that’s been lost in translation – but the end result is essentially a more appealing update of Right Said Fred’s I’m Too Sexy.
As a set-closer, it’s more of a fizzle than a bang.

Image source, Getty ImagesRomania's Eurovision entry, Choke Me, external, has been labelled by some as "dangerous" and "reckless" for lyrics that appear to reference sexual strangulation, external, an unsafe practice that can lead to brain injury and death.
Alexandra Căpitănescu is the artist performing the track - she's a Master’s student at the Faculty of Physics in Bucharest and plans to specialise as a medical physicist, as well as pursuing her passion for music.
She has defended the lyrics on social media.
"Choke Me is a metaphor for the pressure we sometimes place on ourselves," she says.
"It speaks about inner fears, self-doubt, and the feeling of being emotionally suffocated by our own expectations. It was never intended to represent anything sexual."

Image source, AFP via Getty ImagesMost days, Alexandra Căpitănescu is a Master’s student at the Faculty of Physics in Bucharest. But tonight, she’s Lady Gaga and Maria Callas wrapped in Stevie Nicks’ clothing.
Her song, Choke Me, is a rock aria about "taking back control over anxiety and emotions that are choking you".
A real crowd favourite, it’s predicted for a top 10 finish.

Image source, Getty ImagesEarlier in the show, Czechia's performance was interrupted by a technical error.
Looking back at the footage, the picture blurred for a couple of seconds and singer Daniel Zizka disappeared from the screen.
"That did not happen at any of the rehearsals, the distorted picture," said Graham Norton. "I think the camera[man] fell, I’m not quite sure."
We've now heard from Eurovision Song Contest organisers, who had the following statement.
Quote MessageThere was a small camera issue during the performance of Czechia's song at the Grand Final of the 70th Eurovision Song Contest. The artist’s performance and audio were not affected so the song will not be performed again.

Image source, AFP via Getty ImagesI don’t know who Jonas Lovv has fallen for, but I’d like to find out.
According to this song, he’s an animal with no self control. He won’t let go! He knows he’s gonna love it! He’s got some broken bones! (I’m not clear what the last one means, to be honest).
It’s a big glam rock stomper that’s one of this year’s most-streamed entries – with four million plays across Spotify and YouTube.
It’s also in one of the so-called “blessed slots” towards the end of the running order. Could it score big later? Ya Ya Ya Maybe.

For tonight’s third ad break, we get a glimpse of the Eurovision events happening around Vienna, plus a recap of the previous two contests in Vienna – in 1967 and 2015.
It’s a chance to relive some memorable moments, including winners Sandie Shaw and Måns Zelmerlöw.
It also includes, for some reason, Electro Velvet – the 2015 UK act, who scored just 19 points for the UK in 2015.
Barry and his friends are celebrating tonight with pink fizz, sequins and sparkles - they've even got their own Eurovision trophy!

Image source, AFP via Getty ImagesItaly’s song is such a throwback that they’ve transformed the giant LED stage into the creaky wooden floor of a 1970s disco.
But Sal Da Vinci's song, Per Sempre Si, is much more than a nostalgia trip. It’s a tribute to his wife of nearly 35 years, Paolo Pugliese, and a musing on the sacrifices that enduring love requires.
The staging is really sweet, too. As Sal performs in his crisp white suit, a groom paces around in the background, waiting for his bride to arrive. As the song reaches its climax, she appears on stage and they kiss, before spinning around to Sal’s sillky vocals.
How sweet is that?
We've now heard more than 20 performances for this year's Eurovision final.
Moldova, Finland, Poland, Lithuania, and Sweden recently bought their unique energies to the stage tonight.
Here's how their performances were captured in pictures:

Her entry, Jalla, is a hip-shaking Shakira soundalike that references the popular belly dance Tsifteteli.
She performs her pneumatic choreography on top of a giant table - the sort you’d find in a taverna - with added fire effects and pyrotechnics. I just hope someone wipes it down before they serve the mezze.

Sweden has another banger this year and while it's not one of the hot favourites to win, the Nordic country has form when it comes to picking up the coveted Eurovision trophy.
Swedish star Feliciaperforms her song My System in a diamante-studded face mask, which doesn't seem to hinder her vocals.
If it does win, it will move ahead of Ireland for most wins (both currently have seven).
Ireland definitely aren't in the running - they are boycotting the event this year, one of five countries who withdrew after Israel's participation in the competition was officially confirmed towards the end of last year.
