Stop it - you're making me blush!
No seriously, I only picked it up this 'century', from Ian Clark at one of the Soul Essence weekenders probably just before it started rising up in price again, it was somewhere in the five pounds region as I recall.
I haven't played it to compare but think the acetate version will be part two of the single - is the acetate a UK one by chance?
I can't imagine why they had this side done instead of the vocal?
By the way, I don't own the New Moon issue, it's just a picture I got off 'the bay'. I did have a white demo but let it go many years ago and just kept my UK Right on demo.
I would imagine the Portuguese Pye copy was released around the same time as the UK release (Right on being part of the Pye setup) But there again, I have been known to be wrong!
