Watch this classic Town v Scunthorpe United game from October 1970.
Kevin Keegan had given the Iron the lead from the penalty spot after Davidson had handled in the box. Keegan stepped up to squeeze the ball past Harry Wainman into the bottom left-hand corner.
But the Mariners fought back with a Graham Oates brace sealing a 2-1 victory.
