At a range of 50 years, I don't remember many individual games but I was probably at this one. The only name in the line-up that I don't recall from that era is Geoff Ball.
It says sub (singular) not used, so this must have been when one substitute was allowed, if someone in the starting XI was crocked and had to come off. Am I right in remembering that using the sub for a tactical change wasn't allowed at that time?
