The Foo Fighters were performing live at the 2011 itunes festival when all of a sudden Dave Grohl stops the show to kick out a fan who was fighting somewhere in the crowd. We've all been to a concert where some asshole decides to start something & you're there just trying to have a good time. This guy found out the hard way that people won't put up with it, even the band!

Say what you want, Dave Grohl took care of business and the other people who were there to have a good time I'm sure appreciated it. Maybe this will catch on & we'll see more artists performing both on stage and as security from the stage. Personally I think it's funny as hell, but that's just me.
