One of the things that I loooove about the Foo Fighters is that they DGAF and keep it 100!
Case in point: when the organizers of the event they were playing at on Sunday night pulled the plug on their sound at 10pm. Rather than stopping or running off the stage, the guys ran with it and finished out the song, thanks in part to some audience participation. :) Bravo Foo Fighters, bravo.
Song starts at 0:29 Sound cuts off after around the 3:30 mark.
