 Laure Haile, an Arthur Murray National Dance Director documented swing dancing in Los Angeles and used the name "Western Swing".Western swing, country boogie, and, with a smaller audience, jump blues were popular on the West Coast throughout the 1940s and into the 1950s when they were renamed and marketed as rock and roll in 1954.Dancers danced "a 'swingier' more smooth and subdued" form of jitterbug to Western swing music.
