@artemus_5, I forgot about a couple of good ZZ Top stories:
1) At the 2003 SXSW Music Festival, I attended a Yardbirds show at The Austin Music Hall. I sat in the balcony, and a short time later Billy Gibbons sat down beside me. He was accompanied by two gorgeous women wearing tuxedos. It was hard to tell if they were "friends" or "bodyguards" (they were acting very serious). The Yardbirds show featured multiple special guest guitarists, including: Skunk Baxter, Joe Satriani, Slash & Steve Vai. I asked Billy if he would be participating and he said "no, I wasn't asked." I laughed and said that if he showed up backstage, I'm sure he would get an instant invitation.
Ironically, the following year this venue limited their balcony to VIP's only. Even funnier, I told a friend of mine and her friend the whole story. What I didn't know was the friend of the friend had dated Skunk back in the day, and he didn't let her know that he was in town for this gig. She was not pleased about this......Oops, sorry Skunk!
2) My 5th concert was ZZ Top in the fall of 1973. "Tres Hombres" had not taken off yet and they were getting zero airplay in Atlanta at that time. A high school friend had spent the summer in Texas and he came back raving about the band; so, when the gig was scheduled he convinced a bunch of us to go. Tickets were only $5.00, so we figured we had nothing to lose. ZZ Top played their @sses off. While the crowd was small, they were beyond enthusiastic. Everyone was dancing (nobody sitting down) and I recall copious amounts of ganja being passed around. We had a great time and were suitably impressed.
