Is going to see the Foo Fighters. Saw them last night. Dave Grohl is 39 years old. I didn't see that guy stop once all night. For 2 hours, he ran up and down that arena, ad-libbed, sang his heart out, and you could tell he was having a great time.

Not trying to compare Bon Jovi to the Foo Fighters. I'm obviously a bigger Bon Jovi fan, but I'll tell ya - Jon should watch Dave for some pointers on how to show the crowd you appreciate them.
