I was at the chelsea match in 1967 and to my recollection there was around 18000 of us, also the scorer for chelsea that day was Tommy Baldwin who a couple of years later finished up in prison.
I can remember we were mostly under cover in one corner of the ground and during an injury break in the secong half all of the wednesdayites started singing their heads off at which Don Megson turned round with his hands on his hips and stared into the crowd in disbelief.
Was also at Leicester for the Arsenal matches and the Crystal Palace match at Villa park.
Also don't forget the game at Leeds where we won 3-1 after drawing at home with John Ritchie scoring.
