Sitting on the front row of a concert is really cool! I've had the pleasure a couple of times (Kiss and Steve Miller Band). I think the only thing better would be to play with the band (someone hand me a triangle). A fan Dave Groul calls Kiss guy do to his makeup is invited on stage and shreds their song Monkey Wrench! What a rush!
Good job Kiss guy and great job Foo Fighters for giving him an awesome fan experience!
