Foo Fighters' Dave Grohl performed live alongside Guns N' Roses at one of their shows this week.
At one of the band's shows in Tulsa, Oklahoma, Grohl "just happened to be in the neighbourhood" so they invited him on stage. As you do... He helped them out with playing 'Paradise City' and 'Appetite for Destruction'.
