I've heard many versions of "Jimmy Crack Corn" and blue fly and other songs from my childhood. It facinates me because over the years the songs and stories always change. I enjoy telling people where the song " Ring around the rosie" came from. Children sing it while holding hands and dancing in a circle and "sit down" at the end while laughing. They don't don't know what a "Rosie" is anymore than we do. The song originates from the Black Plague times. It basically is "Rings and rings of roses" ( the skin looked like roses when infected) "Pockets full of posies" ( It was common to bury people with posies in ther pockets ) "Ashes, ashes, we all fall DOWN." They burned the bodies of the dead, of course. What a lovely childhood song to teach! Yea, right. Blue Fly and Jimmy have a history of their own also. I wouldn't want to forget the origin, but it will change as years go by. It's the nature of humankind.
