My daughter informs me that Glee is a really cool show. Hm...... I do trust her judgment most of the time. So I went an You-Tubed a few Glee takes and for what they are doing it is ok.  But I don't think puting Foo Fighters, Guns N' Roses or Kings of Leon on the show would matter in the slitest for any of them involved!  The producer of Glee have pissed most of them off.  Calling them names because they do not want to do Glee.  There are just some things that the "Rock World" should not join in on and Glee is diffently one of them.  But to those of you who love the show keep watching and enjoy but you won't be seeing Foo Fighters on that show anytime soon.
