Something I did in my senior year in high school had me on a tight rope where I wasn't allowed to see the now famous ZZ Top tour - something related to my being an adventurous teen much different than my WWI/depression era folks. Before their Madison, WI show my mother stopped at the coliseum to get tickets for something else and you could hear a sound check. We went into the arena and maybe it was evident I was a teen on a short leash or my mother's generally friendly demeanor but someone nodded us towards the stage and they actually played a medley of their then hits for a while and called my mother mam. We stayed for the whole sound check. I did not get to go to the show but could tell my friends I actually saw them. By the time I was a senior the parents had a pretty good idea of what went on at the concerts. Funny to think in the 70s and 18 year old legal drinking, they also let us carpool to shows with older kids before we could drive. It would be someone buying alcohol, someone doing other shopping on campus, and almost always someone puking in a parent's car.
