Leroy "Happy Fats" Leblanc was a Cajun swing musician that recorded with RCA Records in the 1930s and 1940s. He is known for his recordings with Harry Choates and his broadcasts on KVOL. Next to the Hackberry Ramblers, the Rayne-Bo Ramblers were the most popular and innovative of the Cajun string bands.

Harry Henry Choates was an American Cajun music fiddler known as the "Fiddle King of Cajun Swing" and the "Godfather of Cajun music." The scholar Barry Jean Ancelet called Choates "undoubtedly the most popular Cajun musician of his day."
