The Farm’s singer Peter Hooton has helped organise the acts taking part. He said: “It all snowballed really.
"As soon as we got Guy Chambers on board he gave us a studio and his phone packed with numbers for all these A-listers. It just got bigger and bigger. Originally we were going to re-release The Fields Of Anfield Road and we met to talk about that.
“But then Everton FC did the tribute with He Ain’t Heavy He’s My Brother and we were going to do it as a double A-side.
“As it progressed we decided to re-record the track with Liverpool musicians and try to get it to Christmas number one.”
Last year’s Christmas number one was The Military Wives choir with Wherever You Are. Their single sold an impressive 556,000 copies in the week running up to the Christmas chart, more than the rest of the top 10 combined.
Previous Christmas chart toppers have included Alexandra Burke’s Hallellujah which old 576,000 copies in 2008 and Matt Cardle’s When We Collide, which sold 439,000 copies in 2010.
In 2009 there was a surprise in the charts when Killing in The Name Of by Rage Against The Machine beat X Factor winner Joe McElderry by more than 50,000 votes on downloads alone, with more than 500,000 sales.
He Ain’t Heavy He’s My Brother is currently the favourite for this year, closely followed by the Military Wives' Choir, looking to make it a double with Stronger Together.
Project manager Pete Byrne said: “We have had such fantastic backing. Even the guy who got Rage Against The Machine to Christmas number one is helping. Now we just need everyone to buy it.”
The single will be released on December 17 as a CD in shops and as a download.
