That's news to me; and, although I stand to be corrected, highly unlikely.

Ian (Grant) Stewart, who was really a jazz tenor sax player, moved himself and his family from Poynton back to the family home somewhere in Lincolnshire around the turn of the 70's/80's and continued his computing business from there.

Les Renshaw is still in Poynton and, so I'm told, still running a club there; allegedly on the last Friday of the month.
