I saw both legs, didn't have a ST at that time, and had to camp out overnight at the tkt office to get tickets for the away leg. About 20 of us camped out and they bought food out (from the radio station I think!) at about midnight. I only had enough stubs for two tickets but where we had camped out they gave me three tickets for self and both nippers.
Still say that Derby away game, bar the result, is probably my favourite Saints game.
