The Prophets was never released officially on a 45, it's actually The Originals, as to whether you were ripped off, well it's a fantastic record but £60 for a bootleg like this is shocking, I'd sell it you for £15, maybe £20 if it was truly mint. I'd love to know what website you bought that off! The original Marie Knight's are either black issues are white demos but they retain the original Musicor design, your plain one doesn't, as for it not being in the book, if ever you're not sure you can always ask on here and you'll get an answer, there's some very knowledgable people on soul source. That boot is worth about a tenner.
If you want me to edit the original post to just leave the tony michaels, I can.
