My dad went to *one* of those games, not sure which off the top of my head. He’d said that they’d been walking from the railway station to the ground, saw this group of Millwall supporters who looked like trouble coming from behind and so darted in to a chip shop. Which was full of Millwall fans.
They’d asked my dad where he was from and what he was doing round there, he said he’d got a free weekend so decided to come to watch a football match. Him and his mate both had Cotswold accents, so after a bit of questioning they decided to befriend them and invite them in to the home end. They were both very quiet during the game, as you can probably imagine.
He said when Villa scored, the Millwall fans all ran down the pitch to attack the Villa supporters and there was just my dad, his mate, and a handful of old gits on the terrace. Millwall fans came back and the same group were asking why they hadn’t joined in the fighting. They kind of played up the country bumpkin element. Same thing happened again on Villa’s 2nd goal - terrace cleared and just them sticking out like a sore thumb. Made a very swift exit at the end of the game
He can tell that story better than me, obviously.
