I remember watching that on tele. I wasn't sure what game it was, but I remember Big Brian giving someone a real clattering, and the opposition fans baiting him with "Brian Irvine, yer such a f'in penis, Brian Irvine yer a horse's arse!".
I couldn't remember for the life of me who that opposition was, and just when I read your post I distinctly remember a straggley haired gimp falling over, and Big Brian just standing over him shouting all manner of profanities that I'm sure he didn't learn in church!
What a player!!!
