I can remember the occasion of the 91 cup final, but not really the game. The best single match I've attended would be the CIS semi final against hearts at Easter road in 2005.
My son was born a few weeks earlier, so my brother and I had a few pre match shots to celebrate. That year was when this board was probably at its peak, and the cup run added to it, and the atmosphere in the ground was great. The whole occasion of the semi was awesome, and the game itself encapsulated all that is Motherwell, with us throwing away a lead then leaving it to an unlikely hero to pull it back. Then slating said hero for the remainder of his tenure.
Still can't find any decent highlights online to share, although many of us have the dvd, which I'm going to fire on now since I'm working from home.
