Hi Markus, I once had four copies of the Monorays on Astra, funnily all with differently coloured vinyl, golden, green, blue and black. All but one gone.
BUT, theres one on the recent Anglo American list at 100 UKP.

is this only sixties released vinyl on any of the Motown family labels or does it also include the whole Jobete catalogue and say unrel. acetates tracks and LP tracks as well as later released 45s of sixties material such as my recent anniversary ?45 ?
