Phil, going off on a tangent a bit, but what about Swanshurst Grammar? I believe it opened in the mid-fifties sometime and it doesn't exist at all now, as far as I know. (I think it is some kind of school though.)
I hated school with a passion, but Swanshurst Grammar provided us with a very good classical education, though I didn't appreciate it at the time. The headmistress and her staff were so proud of our school. It's a shame that such a good school did not last even 50 years.
