The song, recorded in London and Los Angeles, can already be ordered online at hmv.com, play.com, and amazon.co.uk, and the money raised goes to the Helping Haiti fund. Also singing are Rod Stewart, Michael Buble, Kylie Minogue and Cheryl Cole.
The single is also listed as an import on Amazom.com in the U.S. for pre-ordering although it is not yet clear if it will be distributed internationally as a digital track.
It is one of several fundraising initiatives by the world of pop and film, and its launch coincides with news that Quincy Jones has overseen a new version of "We Are the World" 25 years after the song raised awareness of famine in Africa.
