Whoever the eventual winner of X Factor 2007 is, we now know what they’ll be singing - a re-worked version of the Mariah Carey song ‘When You Believe’.

Songwriter Stephen Schwartz has altered the lyrics especially for the track, which will be released on Monday the 17th of December.

Welshman Rhydian Roberts is currently the bookie’s favourite to win the show, with 80s nearly-star Niki Evans a distant second.

Listen to the Mariah version for yourself below:
