In the mid 1960s the Old Town School Of Folk Music in Chicago had an insignia on it's stationary that looked like a very nice stylized depiction of what most thought was the sun with light rays coming off from the disk. One day I mentioned to Win Stracke something about "the sun on the school's logo." I was instantly informed that it wasn't the sun. It was the pick wheel from a manure spreader!
Folks, what better icon than that is there for a school pushing folklore and songs??
