Peter Berry's book provides the answer to the original question, I believe...
Slightly off-thread, did any of you reprobates rent a room from "Mrs Mac", Main Street, Prestwick (above "The Silver Tassie Bar") around 1971/72?
Charlie, her husband, drove an old Mercedes taxi, and "made a few bob" from ATC Cadets and airport staff.
Some happy sessions in "The Links", amongst other drinking holes...
PM me if you have recollections of same!
