The Norman dean hat-trick was in 66 and was my first ever away game. Following year we drew 2-2 in a friendly(??) arranged as both sides had a free saturday, not being in the FA Cup 5th rd. I also went in 74, 76, 84,04, and 05.
I also went and supported Sunderland in 76 in an evening game with a mackem mate and the following season after we had relegated them to Div 3, my cricket team had a match called off down there, so we went along and joined 50 or so Chesterfield fans in celebrating a 1-0 win.
