I don't know about bringing Jitterbug back but I think dancing is on the upswing with adults. Dancing with the Stars has really brought it to the publics attention. My parents were great dancers. My father in particular, as a young man after the war he used to teach Roller Skating when that was the big craze and he won numerous awards for Roller Dancing. A combination of two popular pastimes in that era.
Here's a great newer song in that style
