I can't see any reason why your choir shouldn't be called a community choir, Marilyn. I'm just curious about the overlap between community choirs and folk music. I guess, because folk music is my passion, I include a lot more of it in our repertoire than some choirs do, and as I love arranging songs, folk music provides a vast source of wonderful material for the choir. However, I suspect that repertoire apart, we'd have a lot in common. I think the key factors for me are inclusivity and no demand for music reading and prior "choral" experience.   If I were more familiar with the classical repertoire I'd probably do a bit more of that as well. I'd love to see your arrangement of Lark in the Clear Air - any chance of an arrangement swap?
