On your point about sponsorship not being allowed on tv, I cant remember who the goalie was but we were playing Southampton when they had Keegan and it was being recorded for the Big Match. Half way through the first half someone realised that our goalie had a sponsors logo on his shirt and he was made to change it.
This one?

Graham Moseley between the sticks I think. I have the programme somewhere if that is the (Jimmy) case.
