I went through a similar security check for the Bobby Davidson match! I can't remember why, but I didn't manage to get a ticket for the United end (even though it must've been an allocation of 6000 in those days!) so me an some mates queued up at Hillsborough. When we got to the front, the keen eyed ticket sales lady tried to trick me as I asked for 4 tickets in the North Stand. "Which fans do you want to be near to, the Wednesday Kop or the United end". She nearly had me, I nearly said the United end and I had visions of the shutter coming down like that twat who hands out treats on I'm a Celebrity. But I had my wits about me and murmered, "somewhere in the middle will be fine". The ticket lady was definitely grimmacing when she handed over those tickets in exchange for my pound coins. What a night that turned out to be, 3-1 to the mighty Blades with a hell of a lot of Blades in the North Stand, (although the blue and white lot will never admit it) to enjoy it with me.
