Alice Cooper - Johnny Depp Performs With Alice Cooper In London

The shock rocker was performing an intimate concert at the British capital's iconic 100 Club, which was recently saved from closure following a star-studded campaign from musicians including Sir Paul MCCartney and Sir Mick Jagger.

Depp, who started his career as a musician, stunned the crowd by appearing on stage with his guitar and joining in with a rendition of Cooper's track I'm Eighteen.

The pair then performed Pink Floyd's Another Brick In The Wall and Cooper's mega-hit School's Out.

After finishing the songs, Depp hugged Cooper, who told him, "I think we could use another guitar player, right? Johnny, this whole movie thing ... If it doesn't pan out, join us, okay?"

The rocker also posted a picture of Depp from the night on his Facebook.com page alongside the words, "Johnny Depp!! Waiting to jump on stage with Alice for 18 and Schools Out!"
