That gig was SD’s second live performance. What actually happened was Baxter accidently smashed the neck of his guitar into the mike causing a short and an enormous fireball. Baxter was knocked flat but kept playing, finishing the song. About a 20 minute break followed before they continued the set. You may remember the opening act - Cheech and Chong. Altogether a very good show.
I don’t remember him being knocked flat, but then again after 50 years I don’t remember too much of anything from 1973. I can barely remember anything from 2022.
I do recall Cheech and Chong being the opening act.
Were you there?
