No Doubt , Ozzy Osbourne and Mötley Crüe are among the artists who have contributed items or concert packages to an eBay auction that will raise money for Donny Silva , a longtime tour-bus driver for many artists who is suffering from stage-four colon cancer.  Proceeds raised will help Silva with his medical expenses, as he has no health insurance.

No Doubt have donated a tour poster signed by every member of the band, while Osbourne has contributed a signed photo and a collection of Black Sabbath guitar picks. Mötley Crüe has offered up a copy of their collaborative autobiography, The Dirt: Confessions of the World's Most Notorious Rock Band , autographed by the entire band and author Neil Strauss .

The auction runs until December 6.
