I read Paul's comment as to the film's location in Liverpool,but the school used was St Mary and St Michaels,Sutton street in Stepney London. the schools name was changed to Scotland rd. I was one of the children who looked on with much interest,and we were watching the catering waggon which had real cream cakes,and suddenly Peter Cushing appeared and told the man to give us a cake each,the man's face turned to thunder. also i remember a stunt man hurt himself falling from the school's window and missing the mattress's. I suppose they use a location,then switch to another like they did with To sir with love.
