I was there! I remember that bizarrely I had to go to a reserve game to get my ticket. It must have been the biggest attendance ever for such a match. Albion reserves versus Notts County with Frank Cronie (?) scoring the second half winner in a dull match.
Albion versus Chelsea? Albion went a goal down but came back and earned a draw; at the time Tommy Docherty's Chelsea was at the top of the 'First Division' so it was a big deal. Sadly we lost the replay at Stamford Bridge 4-0!
Lever - if you haven’t seen it have a look at a thread I opened yday, entitled “Photos - Brighton v Palace and Chelsea” or something like that. I’ll give it a bounce.
