The Hully Gully is a type of unstructured line dance originating from the sixties which consisted of a series of "steps" that are called out by the MC. Each step was relatively simple and easy to do however the challenge was to keep up with the speed of each step.
The Hully Gully was started by Frank Rocco at the Cadillac Hotel in Miami Beach Florida. The rock group, the Olympics, sang the song "Hully Gully", in 1959, which involved no physical contact at all. The same tune was used a year or two later as a song by the Marathons, entitled "Peanut Butter." There was another song about the dance by the Dovells, entitled "Hully Gully Baby" Ed Sullivan mentioned the Cadillac Hotel as "Home of the Hully Gully" on his weekly show, featuring some dancers from Frank Rocco's revue. Known as "Mr. Hully Gully", Rocco then toured America, including the 1964 New York World's Fair. _Wikipedia
