Even if you want to financially support the singer you can buy every CD they ever made for less than a mid-range concert ticket. And all that without some drunk next to you at the show.
I paid major bucks for orchestra seats for an opera at the Kennedy Center for me and a family member. The person seated on the other side of me was a man in a dress, wig and high heels. Deep voice, though. (At intermission, I avoided the ladies' room until s/he was outta there.) So I guess life is like a box of chocolates no matter where you go these days. You never know what you're going to get.
