Well I'll be damned. I used to go to Ivor's shop in the late 60s early 70s - often in my lunch hour. I believe the shop was actually run by his sons, but Ivor was often there, chatting to the customers and playing on the shop's stock. He was a great player and could make any guitar sound good. Yes - I believed he played with McDonough (right spelling?) and made a fat living from his dance band work before opening up the shop. He also did books of guitar arrangements which, I believe, are still available. Nearly bought a cherry-red Gibson SG from the shop but the s/n on the back of the headstock had been tampered with (not by the shop). Did you ever get to Rose-Morris - Adrian Legge's old stamping ground?
