Saw him on many years ago, Loudon Wainwright III (Dead Skunk in the Middle of the Road) was the opening act. King Tut encore.
Let’s get small !
I saw him in HS in late 70’s as well. A bit before King Tut.
LWIII was also on the bill and got booed.
It wasn’t a Martin show, but a benefit so there was also Robin Williams (right before Mork and Mindy) and Martin Mull.
