That's the same fella I remember. I may have been up at Kings Cross that time you mention, but can't really remember - so many rows, so little time back then.
Best I can remember at Kings X was while waiting for our Football Special(s) at St.Pancras to go to Derby, first game of the season, 73/74 I think. There must have been well over a thousand of us waiting outside the station, when we heard a row going on up the road. Turns out Arsenal had gone to Euston to have a drink while waiting for Man.Utd and 'bumped into' the Cockney Reds who were waiting there too. They were chasing each other down the road to where we were, so we chased 'em back up towards Euston.
Upon our return to St.Pancras we found a mob of West Ham waiting near Kings Cross for Newcastle to arrive, turned out to be the first time I'd been in a Chelsea mob which got a result over the spammers! The old bill were going mental as they were far too outnumbered to sort it all out, what with four mobs getting involved - then just to confuse things, a mob of Geordies arrived early at Kings Cross, and it all went off again.
Great start to our day, then we had a rest on the Specials (at least 2, maybe3) before steaming into the Derby mob and rucking with them before, during and after the match. Superb day out, really enjoyed it!
