Back in the late forties Olivia DeHavilland (sp) made a movie titled "The Snake Pit". The heroine was mistakenly confined to a mental hospital -- she eventually shed her fear and fought to reform. The song "Going Home" was their "national anthem" and sung by the patients several times during the movie. It was quite moving, at least it moved me. When I hummed it for my clarinet teacher, he told me the origin. The ways we learn !!
