Alice Cooper was joined on stage by Johnny Depp during his intimate show at London‘s 100 Club tonight (June 26). The actor and occasional musician surprised the crowd when he picked up a guitar and played along for ‘I’m Eighteen’ and a mash-up of ’School’s Out’ and Pink Floyd‘s ‘The Wall’.

Cooper introduced the special guest as “Johnny D from Kentucky”. The shock-rocker had hinted towards the appearance earlier in the night on his Twitter page, writing: “Chuck [Garric, bass] and Damon [Johnson, guitar] go over a few notes with tonight’s Special Guest… Oh, you’ll never guess, don’t even bother.”

As Depp left the stage, Cooper joked: “I think we can use another guitar player. If this whole movie thing doesn’t work out, call us.”

The two will be appearing together in a new Tim Burton film, ‘Dark Shadows’, based on the 1960s American soap opera of the same name, due for release in May 2012.

This tiny show was announced less than two weeks ago, and sold out before an official release was announced. According to the band’s publicist, the decision to play the gig came after Sonisphere Bulgaria was canceled due to logistical problems. With a few extra days off in the UK, Cooper decided to treat his fans to the small gig.

The band’s set included a few of their classics, as well as a rendition of new song ‘I’ll Bite Your Face Off’. They also played quite a few covers from the likes of The Yardbirds, The Beatles, The Animals, The Rolling Stones and The Kinks.

“We’ve been featuring bands that were influential to us in high school,” Cooper said of his song selections, citing them as tracks from the “British Invasion”. He’ll be returning to the UK for a series of Halloween shows this October, joined by the New York Dolls.
