Anders Lind became interested in searching for the history of the dance and in autumn 1983, he found a copy of "Jazz Dance: The Story of American Vernacular Dance" by Marshall and Jean Stearns in an unknown library in "Dansmuseet" (dance museum). Excited about the discovery, he copied three chapters of the book and handed them out to his fellow SSS members. Prior to finding "Jazz Dance", everyone believed that Jitterbug was a dance that originated from the 1940s. They learned from the book that Jitterbug was originally called Lindy Hop and originated in Harlem, NY during the end of the 1920s.
