MickH has a scratchy hissey copy ( on Demo ) of Gwen Owens and plays it. He could get a 'copy' for £20 but he has integrity and carries the spirit of Northern Soul with him. I would be embarrassed and ashamed to play it in his presence. You should therefore assume that other DJs may be carrying an Original copy of what you are about to play out in there box. Don't do it. Have respect for the music. Go to The louvre, they put up a Print of The Mona Lisa but, hey, they have the original in their Vaults. Would you accept that, I think not !!!
