A Live Aid-style single in aid of Haiti earthquake victims is launched today.
The cover version of REM song 'Everybody Hurts', featuring vocals from the likes of Robbie Williams, Leona Lewis and Susan Boyle, will debut simultaneously on the radio and the internet from 8am.
It also includes contributions from boyband JLS, pop star Cheryl Cole, veteran rocker Rod Stewart as well as singers Mariah Carey and Kylie Minogue.
Pop and TV mogul Simon Cowell teamed up with The Sun newspaper to organise the Helping Haiti fund-raising effort, which should see the single released for download on Sunday and in the shops the following day.
The track was recorded in London and Los Angeles.
Up to 200,000 people died in the magnitude 7.0 earthquake on January 12, with hundreds of thousands more left injured and homeless.
