Meanwhile, yes, I remember it played, both at Wigan & Yate.
Think emi discs were taped from cinema ads and after a while, Gordons cottoned on and issued a limited number with a spoken intro "Everones's asking about this sound, what is it, where does it come from? Well here is the sound brought to you by Gordon's Gin!" .....or something similar.
Sure I posted this before somewhere................
