I've told this story so much, my kids roll their eyes:
I was 12 in 1972, and my older cousins lied to my mother and told her I was just going for a sleepover (because I would be dead if she found out where they actually took me). We went to see Alice Cooper (with Captain Beyond and Jo Jo Gunne), and things were never the same thereafter. It was like...wait...you can do THAT on stage? THAT? Holy fuck! Like I said, this was 1972, no internet, no cable, just Alice fucking Cooper. Chopping up dolls, writhing with boa constrictors, and hanging from a gallows. I was enthralled.
By the next week I had traded my 10 speed for a guitar (again, had to lie to my mom and tell her my bike was stolen). I've been playing guitar for over 50 years. I don't miss the bike at all.
