Scot among quartet of The Voice finalists

Stevie McCrorie, a 29-year-old fireman from Clackmannanshire, is the show’s Scottish representative. McCrorie and the other finalists – Emmanuel Nwamadi, Lucy O’Byrne and Sasha Simone – 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 released 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.

The Voice finalists

Stevie McCrorie

The bookie’s favourite is a 29-year-old fireman from Clackmannanshire in Scotland.

He only ended up on the show after his workmates entered him and now is being coached by Ricky Wilson.

Asked to describe his musical style, he said: “Passionate. Dedicated. Unusual.”

Emmanuel Nwamadi

The 23-year-old is originally from Nigeria but is currently studying music in London.

His coach on the show is Ricky Wilson and he counts Nirvana frontman Kurt Cobain among his musical heroes.

He has got strong feelings about the music business, saying: “It is all about sex and that really annoys me.”

Lucy O’Byrne

The 23-year-old Dubliner was working as an usher at a London theatre when she entered the show.

She is on Team Will.i.am and says her musical influences are her father, opera singer Maria Callas and Beyonce.

She claims to be a lookalike for Oscar winner Julianne Moore, saying: “One time I looked at a picture of her and even I thought it was me.”

Sasha Simone

The 25-year-old from Birmingham is training to be a bricklayer and a plasterer.

Her family applied for her to go on the show and she found out only a week before her audition.

She is being coached by Sir Tom Jones, but says the proudest moment of her life was “building my first wall”.
