One of those 1 in a million times where I can correct Reg.
I'm starting to question myself now....I remember there being something about his name, I suppose Will is an acceptable diminutive of Wilfred...
I always used to call one of Wilf's immediate predecessors "Mahavishnu" John McLaughlin, after the guitarist, but not sure many others did. McLaughlin, was another very decent player, who has been largely forgotten. Oh and if you look on Richard B's site for him, he wasn't a left back, but a right back or holding midfield player.
