I came across this video today which features a West Ham United against Manchester United match from 1975, and an unfortunate incident where parts of the ground were so overcrowded that fans were getting crushed at the front and spilling over the fence on to the pitch.
It demonstrates how packed football grounds were and how the police had a difficult time trying to control crowds.
Commentating on the events that day was the late Brian Moore, one of the best English football commentators ever to grace the game.
