I stumbled upon this archived interview on Carmen's fan website
dating back to 1973. Carmen bumps into Kitcat a couple years after
Gracious! folds when he was working for Capitol Records. Carmen
suddenly decided to buy a couple Mellotrons, draft a couple keyboard
players to go with them, and take 'em out on the road! The big
question is: What album(s) did Carmen use this set-up on?
