The Cap Center, now re-re-re-renamed who knows what, is where I saw him the only time I ever did.
In 1981, I saw BOC in the Cap Center, at the end of their giant Godzilla/laser show days, seated up in the nose bleed/pot fumes sections surrounded by a pack of rowdy Marines.
When they did their finale of Roadhouse Blues, the Marines went berserk and briefly “body surfed” me a bit.
Good times.
BOC at Cap?
I saw them there in 77 with Uriah Heep opening.
