My husband and I left after about 15 minutes. I don't know if it was them or the equipment but I couldn't understand them at all.
I really just went to see John Stamos. I saw the beach boys about 8 years ago when we were invited backstage by some roadies (long story but a very interesting night!) We had miss John by 1 day or we would have gotten to meet him!
We did get to see some rehearsal and it actually sounded better in rehearsal than at night. We saw John sing Forever in rehearsal so that was enough for me!
