Dave Grohl is the best karaoke.

If you've ever seen the Foo Fighters in years past, and I'm really talking about pre Dave breaking his leg, you're probably familiar with the drill. The Foo's come out, blow your mind for a few songs, Dave tells a story or asks for requests from the crowd, then they go right back to blowing your mind.

The Foo Fighters on-stage has taken on a whole new life to deal with Dave's injury. Last night the Foo Fighters were playing in Edmonton, Alberta Canada, deep into Rush territory. Dave asks the crowd if anyone can do Tom Sawyer, and so enters Brian.
