Sir Paul McCartney, George Michael, David Bowie and Avril Lavigne are among artists appearing on a charity album to raise money for Iraqi children.

The HOPE album - recorded on behalf of the War Child organisation - was recorded to provide relief for victims of the Iraqi conflict.

McCartney made a live recoding of his track CALICO SKIES. The former BEATLE said, "Whatever the politics, whatever the rights and wrongs of war, children are always the innocent victims. So I am delighted to make this small contribution."
