Irish contestant Lucy O'Byrne will be wired into an electric dress for tomorrow's final of The Voice UK
Tomorrow's final of The Voice is already set to be lit up by finalist Lucy - who will spend an hour being wired in to an electric dress for the show.
The finalists - Emmanuel Nwamadi, Lucy O'Byrne, Sasha Simone and Stevie McCrorie will all take to the stage hoping to win the title and a shot at topping the charts.
Opera singer Lucy will have to warm up while being fitted in to a show-stopping dress of copper wire and electric lights, which takes an hour to put on.
The song list revealing the duets between the finalists and their mentors have been released - with Rita Ora instead performing a lonely solo after her acts were booted off the show.
Lucy will sing a rap and opera 'mash-up' of Habanera from Carmen with Will.i.am, Emmanuel and Ricky Wilson will take on Seal's Crazy and Sasha and Tom will sing Chain of Fools by Aretha Franklin.
Former judge Danny O'Donoghue will return to the show to perform with his band The Script and artist of the moment Paloma Faith will make an appearance.
The four contenders have already recorded their own versions of the winning single but viewers' votes will decide whose is released after they are declared the winner.
Their debut single will be available on the night of the final in a bid to cash in on the show's success and provide it with a hit.
The BBC talent show has come up short in the past in its bid to match the success of acts created by The X Factor, who traditionally release a single immediately after the show ends.
Leanne Mitchell, who won the first series of The Voice, flopped when her debut single failed to reach the top 40 and her album missed out on the top 100.
This year's winning track, which will be available from midnight on Saturday, is a cover of Lost Stars, which was originally by Maroon 5 singer Adam Levine.
Executive producer Moira Ross said: "Having a track released on the night of the final adds even more excitement to the live show. I'm sure viewers will love the track - all four of our finalists are incredible singers and have made their own mark on it with four very different interpretations."
Will.i.am, one of the show's judges, has previously criticised the programme for not having a record ready for release within days of the winner being announced.
