I decided to update my list because I wanted to revive this thread. I enjoy seeing the concerts people are seeing or that they have seen...
Well, if you enjoy it, I'd hate to deny that pleasure...

This is not a complete list, I started keeping track about six years ago... and I've seen many of them multiple times.
