Reminds me of a game I attended at Highfield Road in 1980 between Coventry City and Crystal Palace. Clive Allen's shot hit the stanchion of the goal and bounced out again. The referee, Mr D Webb, was one of the few in the ground who hadn't seen the 'goal' and played on. Coventry were 2-1 up at the time and went on to win 3-1. Unfortunately for the referee, MOTD cameras were there and his error was seen by millions. The incident did result in the design of goal stanchions being changed, I believe.
