Well, there were a few djs getting emidiscs cut, became a popular and cheap way of gaining access to the big sounds being played, deffo up to around 78/9 i reckon. Never seen an emi of the Belles band...only the first of the ss acetates.
I'm pretty sure i enquired with Ady as to why it hadnt appeared on either of the Mirwood/Keymen cd comps he put out, a number of years ago now....but, as i said, Simon did a deal with Randy Wood snd when i asked him ( Simon ) he said he still had the backing track so....probably what was being looked for in their archive but they couldnt fjnd it.
