I hope Frank went out with no regrets, he certainly seemed to have an awesome life.
Back in '76 or '77. I saw ZZ top in Nashville with their worldwide tour. It had a massive stage shaped like Texas, vultures on stands around the stage, and during the break a female coyote Wrangler came out and had some coyotes do tricks.
J. Geils band was the warm-up
Saw them again in the '90s on their recycler tour, I think at the Oakland coliseum. They drove around the stage in little crushed car cubes.
Those dudes knew how to party and had an awesome sense of humor
