Back in the 70's I saw ZZ Top in Tulsa, OK. The concert blew me away. There was a plexiglass pyramid on the stage with a rattlesnake in it. A buzzard on a perch sat behind (or next to) Frank Beard. And then on each end of the stage were these black curtains and up rises a Longhorn and a Bison. I do not remember the year or the tour...but I am hoping someone out there does!! Anyone?
