Ive seen u2 and Clapton on your guys list. Both great

See, some bands play concerts, others put on shows.

I saw grateful dead a number of times, they were great for a concert.

But I have seen Springsteen over 30 times, and it's an experience.

4 hours of bliss. and who enjoys playing more than he does, he aint doing it for the money anymore, thats for sure.
