I went to college there too, I was sent for one year by the GPO, I was 17 when I started there when I began as a telephonist at telephone house, they made you go to college till you were 18.Yes, I knew much of the Bournville estate was Cadbury built and 'owned'. I went to college there for a while and a resident worked for my father. It is a lovely, generally unspoilt area and when I travelled north by train I could see much I that I recognized was still there. I used the sports facilities and baths there and am very pleased that much is still in use.
My Grandad,s name was Cyril Cooper and he played either violin or viola and his father Harry Cooper who played the cornet. I don't know anyone else on the photo.Can you give a name, when linked with an orchestra it may shed some light. There was a Bournville Orchestra but may not have been connected with Cadbury.
