Eurovision: Olly Alexander gives fans an idea about UK entry Dizzy

Singer Olly Alexander has sent Eurovision fans on a roll by revealing the chorus to his song Dizzy, which he will perform on behalf of the UK at this year's song contest in May.

Previous Years and Years frontman Posted 20 seconds For a vibrant, club-friendly pop song on social media.

It was also announced that the full track will be available on March 1.

Despite only hearing a snippet, some fans are beginning to speculate whether he can end the UK's long wait for victory.

“WINNER EUROVISION WINNER FOR SURE,” one user enthused on Instagram.

But they added: “Of course, I would never put the UK in the context of winning Eurovision with something like this, and it won't happen. I'm not sure about the top five. It has to be carefully orchestrated and convincingly sung!”

Co-host Raylan had an advance copy. “I've been singing this song for months, it's so catchy.” he wrote.

In the video, Alexander is seen performing the song on a rooftop at night wearing a striped jacket with cut-off sleeves, a matching skirt and a homemade pink badge.

He sings: “Will you make me dizzy with your kisses / Will you take my hand and spin me around / Round and round until the endless moment ends.“

The song fulfills his promise in December that the song “isn't a ballad” but will be “electronic, something you can dance to.”

It was co-written by Alexander and Danny L. Harley, who has produced hits for Dua Lipa, Chic, and Charli XCX.

Alexander will be hoping to improve on the UK's disappointing performance at last year's Eurovision, when May Muller came second to last.

The UK has not won since 1997, and its recent record has been largely disappointing.

The English singer's teaser clip came several hours after he posted a message bearing the title and release date, accompanied by a photo of himself upside down on a swing wearing nothing but a kilt, torn socks, and one shoe.

This may or may not be a clue to the performance routine he intended to perform at the grand final in Malmö, Sweden, on May 11.

Alexander is already known to music fans across Europe for his singing of Years and Years songs including Desire, King and If You Over Me.

He is also a BAFTA-nominated actor, having played a lead role in Channel 4's powerful AIDS drama It's a Sin.
