Ballakermeen 92-99 here,
had woodwork with Benny Ball a few times, didn't he not miss a single lesson in 25 years? (or something like that?)
also, wasn't there a teacher (female, 40's, long gingerish hair, did craft/cookery) who was found to be using a false name, as well as qualifications? -- she vanished halfway through a term and myself and 2 friends got a shouting at for even asking where she was! (we 6th formers had to 'guard' the fire alarms on the last days of term, she brought us mince pies )
plenty of psychotic people (teachers & students alike) there though!
