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".
A statement on the Choirs With Purpose website said that the single and subsequent album was made in response to "recent events which have threatened the peace and unity of our communities."
"[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.
Ms McManus said she was "delighted" to feature on the charity single in an article in the Evening Times.
"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."
MEET THE CHOIRS
Lewisham and Greenwich NHS Choir
Made up of NHS staff in Lewisham and Greenwich, this choir made it to the Christmas Number One spot in 2015 with A Bridge Over You.
The choir was helped along to succeed after chart rival Justin Bieber tweeted his fans encouraging them to buy their single.
Since then, the choir has appeared at Glastonbury and performed at the FA Cup Final and has even signed to the same record label as Justin Bieber.
The Missing People Choir
This choir, made up of friends and family who have had someone they love go missing and staff and supporters from the Missing People charity, appeared on this year's Britain's Got Talent.
The choir was formed in 2014 to raise awareness about the charity by James Hawkins and Clare Cook, who have produced 'Stand Together'.
The Parrs Wood High School Harmony Group
The Manchester choir made up of young people from Parrs Wood High School released a cover of My Everything by Ariana Grande in response to the Manchester attack.
The aim was to raise funds for the victim’s families and support with ongoing financial costs. A number of children in the choir were also at the Manchester Arena concert.
They were later invited to perform with the star at the One Love Concert in Manchester.

Since his death, his mother and father Tim and Fiona set up the DSM Foundation, a drug and alchohol education charity in his honour.
The charity now works with over 100 schools, colleges and community groups.
The Games Maker Choir
