It looks like the power of his oxycodine-induced, self-designed throne has gone to Dave Grohl's head. At a show last week, he generously allowed a fan to play the drums for the old Foo Fighters hit Big Me.
There's no telling what happened to the regular drummer, but the possibility exists that they fell off the back stage and were not given the luxury of having a tour throne built for them.
These images are floating around Reddit at the moment, acting as a sort of cautionary tale for either falling asleep in public or drinking too much. Or both. Pictured is The Maccabees drummer Sam Doyle missing his chance to meet Dave Grohl and John Paul Jones.
