I saw this ad a few times in 79, and it was also reworked into their concert appearance as well. I so wanted to see this show, but after learning of all the stuff going on backstage, well, I don't mind not seeing it that much now.
I sure would have loved it then, no doubt about it. there was just a magic about music then, when you couldn't find out every detail about infighting with band members or drug use or what have you. and being 14 helped!
