During a dry spell for them they played a backyard party for a kid in the neighborhood I live in now in the late 70s. My MIL was there and asserts they were "perfect gentleman".

Interviewer: Why don't you wear a long beard like Dusty and Billy?

Frank Beard: Mom says I'm way to pretty to cover my face will all that hair.

Interviewer: What is the smallest crowd you played for?

Billy Gibbons: 1. It was at a county fair. He was by himself in the crowd. We invited him onstage. He would name a song and we would play it. After about 30 minutes he ran out of songs of ours he knew, said "Thanks" and went home. So did we.

Guy I used to work with was a bell boy or whatever you call them at a fancy hotel in downtown Dallas. The guy that carries your bags for you. It was a weekend gig during HS that supposedly raked in much cash.

One weekend ZZ Top and The Grateful Dead were in town at the same time. This guy makes a room service delivery to Billy Gibbons room. BG comes to the door then steps out into the hall in his underwear, a hat and a guitar slung. They make idle chat while BG strums along. As he was leaving, friend tells BG, "Hey Jerry Garcia is across the hall and a few doors down from you." BG replies, "Is he fatter than me?" Friend responds in the affirmative. BG goes back in the room, comes back, hands him $20 and says "Good answer young man." Then goes back in his room and closes the door.

This guy met all kinds of bands that came to Dallas at the time. His autograph collection is something to see.
