I recently picked up this 45 in a batch of stuff, but have no idea whether it's someone's dodgy boot/carver or something of interest. It feels like shellac rather than vinyl and has hand written titles - "You've got the upper hand" by Candi Staton; and "Put me in your Pocket" by Jeannette Harper. Other than that, it has a distinctive logo, and printed type - Demonstration Record. Sound quality is not great, but playable. Anyone seen anything like it?
