Some stoner in back would light a doobie, take a hit, and pass it around from person to person. 100% of the time, when it came to me, I said no thanks and passed it along. No way. I've been going to concerts for over 50 years and the shows back then were very different than now. Louder than hell. A haze permeated over the venue. Objects getting thrown in the crowd. Loudest concert I ever attended was Uriah Heap with Deep Purple as the headliner. We had fifth row center. The blazing sound of "Easy Livin'" still rings in my head all these years later.
