Josephs record Children in Need single
The winner of Any Dream Will Do will also be the star of this year's BBC Children in Need single.
The three remaining hopefuls - Keith Jack, Lewis Bradley and Lee Mead - have each recorded a version of 'Any Dream Will Do', the much-loved song from Joseph and the Amazing Technicolor Dreamcoat that became a number one hit for Jason Donovan in 1991.
The winner's version will be released as a double A-side single alongside an ensemble performance of 'Close Every Door', the TV talent hunt's exit number.
The single will be available as a download from June 12 and in the shops from June 19.
