CB,
I grew up with Brother Dave's classic LP "Kick Thy Own Self" on the family stereo. Yer right, PC he never wert, but brilliantly inventive he was - and a trap drummer before he ever trod the boards as a comedian.
Also, either or both of you might get a kick out of the several "Congress of Wonders" LPs from the eponymous Bay Area duo dating from the late 60s...some very inventive acid-etched wordplay came from that pair, too.
