I live in St Paul. In the 70s I knew a friend of the BB who had a monster basement sound system that I sold him along with a dude named Bob Rolle. I'll try to contact the friend and post more depending on his privacy concerns.
You sold him a sound system along with Bob Rolle?...I wonder how Bob's parents felt about that?
Seriously though, it would be great to finally have this mystery solved.
How did you find this place, much less this old thread?
