Clearly the 'us' in the Folkarts England peice Crow Sister quotes refers to all the people making, promoting, listening to and enjoying the music. It's nothing sinister and doesn't imply an excluded 'them'. I'm not and never have been a folkie and have no desire to become one (labels don't really become me...) but have never felt like I've been left out of someone else's party when I've listened to folk music. It's only music.
