Australia’s Guy Sebastian will sing a contemporary R&B track called 'Tonight Again' at the Eurovision Song Contest held in Vienna, Austria.

Take a look behind the scenes at 'Tonight Again' coming together in the video above.

Australia’s first ever Eurovision entrant Guy Sebastian has released the song he’ll compete with in Vienna.

Tonight Again has been described as a contemporary R&B style track and one that belongs on the Eurovision stage.

“I thought since I had a couple of days off in Australia I would try and write something new,” said Sebastian.

“We all have moments you don’t want to end and you wish you could live those moments every day so I wanted to write a song about that feeling.”

The track was written, recorded, mixed and mastered in the 48 hours prior to submitting it.

“Tonight Again is a song we can all get behind, and Guy is the perfect artist to deliver a world class performance for Australia and SBS on the world’s biggest stage,” said SBS Managing Director Michael Ebeid.

Sebastian will be fast-tracked to the Eurovision 2015 Grand Final as a special one-off wild-card entry.

He’ll perform to a packed Wiener Stadthalle stadium in front of an estimated television audience of almost 200 million people.

"Guy was initially thinking of a power ballad, but this new song is a celebration of the grand final night and our participation, and we couldn't be more excited about it," said Director of Blink TV, Paul Clarke.

Australian audiences first discovered Guy Sebastian when he was crowned the first winner of Australian Idol in 2003, he has since gone on to release 8 studio albums with Sony Music Entertainment Australia, with accumulated sales in excess of 3.7 million units.

42 platinum and three gold certifications Guy has become one of Australia’s most successful male artists. In 2013, his single Battle Scars went Platinum in the US, making Guy one of few artists in Australian music history to achieve this. His performance at Eurovision is an incredible opportunity to introduce Guy to European audiences.

Guy has released several songs in Europe over the years with Battle Scars being the most successful. From his current album Madness, both Like A Drum and Mama Ain’t Proud have graced the air ways and continue to expand Guy’s audience across Europe.

This is the first time Australia has been able to compete and vote in the contest. It follows a special performance by Jessica Mauboy at last year’s contest in Denmark.

Australian fans will be able to watch Guy Sebastian perform at the Grnad Final live on SBS One on Sunday May 24. Get all the details on how to tune in.
