Having rediscovered this thread, I note that Simonp mentions the name Tony Zemaitis. I am sure this was the same Tony who worked in Emile Grimshaw's workshop fixing guitars... winding coils for humbuckers and so on. He was also a guitar player, of course, and was playing somewhere in London at the time, I recall. I don't think he joined his employer's little band... perhaps a bit too old-fashioned for him, as no doubt for me too.
I was playing at The Grotto Club in Baker Street... an amusing residency for over a year... a Roman Catholic Club indeed. One of its regulars who used to sit in on bongos was John Junkin (later in 'A Hard Day's Night' with the Beatles, who he knew from his youth in Liverpool.
