I must agree about the zombie part..
As I am 23 and digging 70s rock bands it's hard for me to see most of them cause they are either dead or quit.
I must say after looking at the who and Pink Floyd at Live 8 and Queen doing new stuff with Paul Rodgers, they don't move as much, but they still keep the rock alive!
I've heard Deep Purple is still touring as well.. It all goes well till Ian Gillan tries to do Child In Time as in the glorious days.. I wonder if he still wears the tight tigerprint pants. Any confirmation? lol
And of course Led Zeppelin really rocked during the reunion, Plant going solo is a bore to watch though
