I saw Leeds play at Selhurst Park, I think it must have been this game, got there after the start as the crowds were enormous. I left for Aus in 1966 and saw the great Leeds team play at Selhurst Park.
There was the little inside forward, Johnny Giles playing and their goalkeeper was who, a Welshman, a bit unpredictable, began with an S I think. Bloody hell, a long time ago, over 45 years.
I didn't watch the Pathe News clip, it took an etenity to load, I gave up.

It was Gary Sprake - I was at the game but don't remeber too much about it (probably because we lost) but the earlier rounds were also memorable. I remeber going to Southampton where we won 2-1 then a great game beating Forest 3-1 at Selhurst.

I think we beat Forest in the previous round 3-1, i didn't get in for the Leeds game after waiting in line for four hours for a ticket.

It was played in front of over 45.000 and the Forest match 42.000 both record attendances.Holton scored in all three of the previous cup matches.
