I remember being shusshed in the North (geriatric) stand at Withdean on one occasion.I was at the U/21 England v Norway game, standing on the West stand terrace. From what I remember, the attendance was 18,000+, we had just installed new floodlights, and there was a bloke next to me complaining that the crowd was too noisy!
I was so surprised I had to do a double take to make sure I was watching the Albion and hadn't stumbled over the road into the bowls enclosure and fallen over some duffers watching in deck chairs, when I'd left the pub before KO.
It was like being at an orgy and being asked to 'put that frightful erection away'.
