I'm sorry you had to sit through that nuisance, Banjo. I agree that it is inconsiderate and distracting to others to take an excessive amount of pics. I think if I was in that situation I might have considered speaking up and politely but firmly ask that he keep the picture-taking to a minimum.
As far as the sound, I also agree it could have been turned up a notch. Especially since there was a drunk guy in the audience who felt the impulse to yell out at the top of his lungs "I Love You Gordon!!" about 15 times in the first half of the show, usually when Gordon himself was speaking.
He was removed eventually but not until intermission and not before he spilled his drink all over the people sitting next to him (as he was being removed).
