Ok, I'll post this again...
Mike Rutherford is actually who led me to Alembic. I saw the list of equipment in the Abacab Tour brochure, and had to check them out...and now I own 4 of them. BTW, when they came to the bay area that year, it was 1982, and the 10th anniversery of Foxtrot. Supper's Ready live is breathtaking.
