Hi Dave,
I've had a thunk about this and remembered why we (Mick, Wid et moi) didn't bother with the shop too much. I actually had every UK Tamla release by then so I would only need to buy to resell -which was my full time job at the time. I remember they put the prices really high (relatively for London) so there was little margin for profit so I wouldn't spend too much time up there. I'd have obviously snapped up the Jimmy Thomas issue but you can't be everywhere at the same time. There were a lot of great finds, UK labels in particular, in London in those days. Ady
