I'm impressed by the clear memories of some on here. I really struggle to remember my first match - and it was only in the early 90s! I was a kid though so understandable.
My main memory was that Tommy Johnson sat next to me in the stands and asked to borrow my programme. I don't know if the fact he was a spectator means it was around the time he was leaving the club in 1992. Or he could have been injured..? I clearly remember some of the games from the season after that so it was definitely around that time.
