He seemed to sell an acetate then miraculously he'd find another copy if two people wanted the same one.
One authentic thing he did send me though, was the original acetate of jenny Wren - Chasing My Dream All Over Town, it was by Barbara English and was the only recording of it in the world - unfortunately half the lacquer had peeled so only 90 seconds of the song existed. No idea what I did with it, might be on that old PC Simon!
