Which branch does Jitterbug belongs to?

The Jitterbug has been around since the 1930's. It came out of the Swing era of music when the Lindy and East Coast Swing was popular. There was a scene in "The Wizard of Oz" back in 1939 that was cut from the distributed movie, it was called the Jitterbug with a big dance number and song to match. I have an anniversary release of the Wiz of Oz that shows a lot of the scenes that were cut from the movie. It's too bad they didn't leave it in, it was pretty cool. My mother taught me how to dance the Jitterbug when I was a kid back in the early 60's. I very much enjoy it. I'm glad to see it never really disappeared all these years, even some of the disco dances of the 70's were based on old Jitterbug moves. I'm glad you enjoy it so much, it's a lot of fun and great exercise!
