Alice Cooper

Johnny Depp, Sebastian Bach, Don Felder and LA Guns jammed with Alice Cooper and his band on Saturday night at Alice's twelfth annual Christmas Pudding extravaganza at Comerica Theater in Phoenix, Arizona.

Here's fan-filmed footage of Depp playing "School's Out" with Alice and co:

Proceeds from Christmas Pudding go to Alice Cooper's Solid Rock, a non-profit organization dedicated to enriching the lives of teens through music, dance, and self expression. It was founded by Alice.

Depp is becoming quite the Alice axeman of late: he jammed with the band on November 29 at the Orpheum Theatre in Los Angeles from the "Raise The Dead" tribute section of Alice's show onwards.
