They used to sell what were called Eckies behind the bars of New York gay clubs and there were a lot of straight people would go for the music made better by what was stored in a jar in the bar and cost the same as a pint. Muscle Memory was the first time I had heard of such a thing as people of the same denomination would come up to you and say "do you want Muscle Memory"  and I would politely make my excuses and like a tree "go". I have practiced Nonanism for 352 days. There was a club in Amsterdam called Club Red where there was a guy who was doing the business in there and he had a stutter and let you try his wares for free as he reckoned the things he pedalled were so good you would come back for more and we seen him get a girl that was involved and there was a bag snatch on her but there was about 7 guys who were all over it straight away.
