Word got to the elders that 3 of my friends and I were going to one of those "rock concerts". We were all hauled into the back room and told how we were supposed to be role models for all the younger ones (we were all 20 or so at the time) and also worried we were going to try the pot at such a worldly place.
One of us backed out but me and two others went. Epic show of Deep Purple with the classic Blackmore, Gillan, Lord, Paice and Glover line-up.
We went to a bunch of other shows over the year. Never was a word mentioned to anyone so no need for further counselling.
