My old man was one of them and he's currently residing in Woodvale Memorial garden, so that's one less to find. Not that he was that impressed with Crumplin's strike - Johnny McNichol had scored tonnes of them, apparently. The greatest ever Albion player etc.
I've just checked Tim Carder's Seagulls book and it was Boxing Day 1992! 28,700 in the crowd. My mistake, 8,700 in the crowd! At least 75 from Burnley though. We won 3-0.
I was gonna nominate this - it was the first one that sprung to mind. That and Crumplins goal against Burnley (I think) on Boxing day in 1990 something, unusually I was stood in the East terrace and got a perfect view.
