I was 15 and had a junior season ticket in the Canton Stand, block C I think. I was 2/3 the way up the stand right in the centre when Brian Clark nodded in that goal. Great night and the official attendance was 47,500 but seemed more.
The following season we had 50,00 v Leeds in th F A Cup, but that wa even more crowded, and my fourth game in January 1969 was in the cup again v Arsenal when there were over 55,000 there...that was really crowded and scary.
