UK's Eurovision Song Contest hope Electro Velvet have put in their bid for the winning performance in tonight's competition in Vienna, Austria.
The duo offered a kitsch staging of their song, Still In Love With You, complete with electric violins, light-up dresses and backing dancers showing off a Charleston-inspired routine.
Alex Larke and Bianca Nicholas were the fifth act of the night to take to the stage in the Wiener Stadthalle, where they performed their electro-swing track which was written by David Mindel and Adrian Bax White.
Nicholas, who has cystic fibrosis, may be familiar as a former The Voice UK contestant, while Larke's day job is as a primary school teacher who moonlights as Mick Jagger in Rolling Stones tribute act The Rolling Clones.
The song got a positive reception from many, with Fern Sargeant commenting: "Loved Electro Velvet - it could be the Fact I was born in the wrong era. There's nothing better than (electro) swing...." while James Head added: "Electro Velvet did GBR proud.. Well staged performance, very catchy. Hopefully it turns into votes!"
However, some viewers seemed confused by the unusual style which Electro Velvet went for.
Charlotte Ferrer tweeted: "Appalled by the UK's Eurovision entry. How unpatriotic am I tonight?!
Sonal Raja posted: "Why do we always get it so wrong? Electro Velvet were truly awful! Oh my ears."
There are 27 acts performing at Eurovision tonight - 20 who made it through from the semi-finals earlier in the week, the "Big Five" financial backers UK, France, Germany, Spain and Italy, last year's winners Austria, and special guests Australia.
Last year's winning singer Conchita Wurst is one of tonight's hosts, while Graham Norton is presenting the UK's TV coverage for BBC One.
