It’s the live final of Pitch Battle, airing on Saturday 22 July on BBC One.
Host Mel Giedroyc is joined by a trio of musical judges: the nation’s favourite choirmaster Gareth Malone, former choirgirl turned international recording artist Kelis, and guest judge, the Pitch Perfect Deke Sharon. Between them the judges will whittle the six final choirs down to the top two through a series of head-to-head, sing-or-be-sung-off choral challenges – leaving the viewers to pick the ultimate winner.
The final opens with an epic musical mash-up, then each group will collaborate with a Superstar – which includes Will Young, Chaka Khan, Bebe Rexha and Seal among others – in a Showstopper.
Then the groups will battle it out against their opponent in a themed riff-off.
The judges will then decide three winners to send through to the a cappella round, and after that which two are the best.
At this stage it will be thrown open to the public to vote online to crown the winner of the £50,000 prize and the title of Pitch Battle Champions.
Pitch Battle Episode 6 (of 6) airs on Saturday 22 July 2017.
