If you could go back in time and watch any band / musician play live, who would it be?  Reason I ask is because I am going to see a Led Zeppelin cover band, Led Zepagain, tomorrow night.  It would be awesome to go back and time and see the real thing.  Anyone lucky enough to see them in their prime? 
 

For me, it would be a tough choice between Zeppelin or C.C.R., what does everyone think?  I am doing my best to clear the recent thread list of Weber..
