I was out for a bike ride at the time and I could hear the crowd from about 3 miles away.
Fairly recently, I found the entire match on Youtube and watched the lot. Quite entertaining.
I think that may have been the season in which I went to watch Sunderland, with My Mate Terry Who art in Sibton, play at Roots Hall. It was one of the first matches of the season and Southend won 3 - 1. The waifs and strays who had made the journey were chanting helpful things like "You're not fit to wear the shirt!" At the end of the season Sunderland were champions and Southend relegated.
