Well, you're in the minority. I saw them at MSG when I turned 18, which was almost 30 years ago. It was the best concert I've ever seen. So outrageous, and fun. You have to give credit to any musical group that survives so many decades.
I saw the Stones back in 1981 when I was 14 and thought it was a great show. Then I saw them again in 1989 (after ticket prices had gone through the roof) and thought they sucked. Possibly the best concert I ever saw was Pink Floyd back in 1987, but I had a whole bunch of chemicals in me that night!
