If it's Kev's I had a good look at it on Saturday night and I'm convinced it's dodgy.
Because:
1) It is vinyl with moulded on label not styrene.
2) The ZTSC number is scratched on.
3) It looks and feels too new and fresh (subjective I know).
4) The sound quality is appalling.
Compating it to mine, the label is a fuller red colour, it's styrene with ZTSC number stamped and it plays clear as a bell.
I reckon it's either a boot or a counterfeit. In the case of a boot I can't understand why anyone would want to, it's not rare and copies are easily available. If counterfeit well, there are a myriad of reasons why artist, staff, musicians would want to do this but I'm not convinced due to the "newness" of it. I concluded it was an ill advised boot from the 80's and dubbed from an original record.
If I'm wrong well at least I bumped your post so we can get some other views.
Best,
John.
