I saw him when he played my town (Rochester, NY) a couple of years ago - it was great, but I really didn't feel the need to see him again. Maybe others felt the same way. It was just kind of a full-circle thing - I saw him in NYC back in the 70s, and for nostalgia's sake thought it would be fun to go once more.
I wish he hadn't had so much plastic surgery and I also wish that he hadn't done that part of the show where he sang with the video of "young Barry." That really pointed up the difference in his appearance. I also thought it was kind of creepy when he descended from the stage in that little cage and pulled someone out to dance a slow dance with him. Awkward! I never, ever thought of him in the same category as my other teenage crushes (Peter Frampton, etc.) I just loved his voice.
I have to add that I'd say most of the people there when I went were in their early 50s, like me - not "blue-haired" senior citizens
