Singers spearhead tsunami benefit

Elton John and Andrea Bocelli are joining several other major recording artists to produce a cover of Eric Clapton's "Tears in Heaven" to aid victims of the Asian tsunami.

The single is an initiative of Sharon Osbourne, wife of rocker Ozzy Osbourne, and proceeds will go to benefit aid organization Save the Children's operations in tsunami-affected regions.

John and Bocelli were recording their tracks in London this week. Additional recordings -- with singing from Pink, Rod Stewart, actor Robert Downey Jr., Ozzy and Kelly Osbourne, Gwen Stefani, Phil Collins, Josh Groban and Aerosmith's Steve Tyler -- are planned in Los Angeles next week, organizers said.
