Video report by ITV News correspondent Ben Chapman
A supergroup made up of 10 choirs across the UK and a Pop Idol finalist are to release a cover of a Paul McCartney song as a charity single in a bid to make the Christmas number one.
'Choirs with Purpose', made up of 10 choirs including a Britain's Got Talent finalist and a choir that beat Justin Bieber to be 2015's Christmas number one, are to release their single 'We All Stand Together'.
Pop Idol winner Michelle McManus, whose debut single made the Christmas top spot in 2004, is the lead vocals on Paul McCartney's 1984 'Frog Chorus' song.
The single brings 14,000 voices together to "sing for peace and unity".
"[It] is all about hope in a time of uncertainty, division and conflict," it said.
Sir Paul McCartney has waived all royalties from the single sales so that proceeds could go to charities including One Love Manchester Appeal and Missing People.
"It's been another tough old year with tragedy after tragedy happening all around the world and somehow the words in this song, written more than 30 years ago, are as real today as they were then," she said.
"No matter what we all do, we should stand together and it has to be love over hate every single time."
