Guns N’ Roses kicked off their reunion tour with a surprise gig at the Troubadour club  in Los Angeles Friday night.

Joining original members Axl Rose, Slash and Duff McKagan were keyboardist Dizzy Reed, guitarist Richard Fortus and drummer Frank Ferrer.

A no camera policy was announced, but a few fans were able to sneak snippets of the performance, which have been posted on YouTube.
