A big thanks for all the comments on this one guys - really interesting stuff and much appreciated
I also got some really useful feedback from Canada and from a number of well-known Detroit collectors - with a mix of views on this one. The only thing that everyone I spoke to agreed on is that they hadn't seen it before.
I think the majority view was that it is probably an original issue and most likely a legit forerunner to the later deal with Quality Records in Canada - in much the same way as the London deal went for the UK release.
I'm very grateful especially to John Manship for looking at this one for me. John was guesting on Dean Anderson's Northern Soul radio show here in Newark during the week, and so as a local lad I was able to pop down with the 45.
John's view, with the 45 in hand and looking at the paper/vinyl etc., was that it is a definite 60s original - which is good enough for me - and obviously I'm pretty chuffed with that
Cheers
Richard
