Sharon Osbourne's charity single to raise money for the victims of the Asian tsunami and Hurricane Katrina is being released today.

The single, which is a cover of Eric Clapton's hit 'Tears In Heaven', features performances from Elton John, Mary J Blige, Gwen Stefani, Ozzy and Kelly Osbourne, Pink, Katie Melua, Andrea Bocelli, Phil Collins and Robert Downey Jr, with music by Velvet Revolver.

All proceeds from the sale of the single, which will be available to download online, will go towards the work of Save The Children.

Sharon Osbourne said: "The magnitude of these natural disasters surpasses anything we've seen in our lifetime."

"With this single and other relief efforts, our intent is to keep these tragedies at the forefront of everyone's minds. We must not forget and do all we can to help these people rebuild their lives," she said.
