Arthur Mann! Now that rings a bell. At the time my mother was Assistant Supervisor in the canteen at Manchester Education Offices and Arthur's missus (whose name I don't recall) worked as one of her underlings. Imagine that today! Why, it's as easy to imagine the Duchess of Cambridge scrubbing floors for a living.
I quite liked Arthur as a player, but he never seemed to get many opportunities, maybe because he wasn't up to it. (It's an odd thing, but City seem to have a hereditary issue with fullbacks. Very few, especially left backs, have been top drawer. You can almost number them on one hand, no matter how far back you go.)
