I too went to that game, and boy were we unlucky!!
I recall Steve Heighway was the difference for them. We went over the pennines in the back of an old van. Cold aand dark, and a long way back after. Extra time and such a disappointing result.
All I can recall about Sutton is that he was always very much a fringe player and on featured that night a a replacement for anothet of our farwards. (sorry but cant remember who. It was a long time Ago)
Not much help I know but thanks for the memory
