Bright spark Lucy O'Byrne to power Voice with electric dress
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.
This year's winning track, which will be available from midnight tonight, is a cover of Lost Stars, which was originally by Maroon 5 singer Adam Levine.
