My son attended a school for learning disabled children. Music was a uniting force. These were children who for the most part were ostracised from "normal" social interactions with other children. But at the school, folk music, rock, rap, whatever played a critical role in helping them to learn how to behave is a common social setting.One friend knows the lyrics to every 50s record ever published. It gives her such joy.
The school accepts donations of used instruments for their orchestra. Recently, I found a flute for them that turned out to be worth something. They sold it and bought much needed refurbs.
If you enjoy your work even half as much as the people benefitting from it, you must be a happy lady.
