ZZ Top played a concert outside my dorm during my freshman year in college at Baylor University in 1977. At the time, Baylor (a Southern Baptist school) was toying with loosening up their straight laced reputation (no dancing on campus) so as to appeal to a more diverse range of students (like me). Having ZZ Top play was an experiment — a short lived experiment after a cloud of pot wafted across the quad.
ZZ Top never played Baylor again.
I lasted three years before transferring to UT.
