Note that these two songs, as well as a few others I'll list below, are all derivatives of an old Appalacian folksong called "Rubber Dolly". These songs are like off-shoots from this extremely popular melody. I like this because it shows how American vernacular infiltrated the popular tunes of the 1920s in Cajun areas, each in their own unique way.
The first recording of this melody was by Angelas Lejeune in 1930. He got the name from Lafourche Parish comedian named Walter Coquille's radio program in which he jokingly referred to himself as the mayor of a fictional town called Bayou Pom Pom. The name Bayou Pom Pom (or sometimes spelled Pon Pon) refers to the bayou called Bayou Pompon, located east of the town of Chackbay. Although there is no such town, Walter used this for his comedy recordings in the 1930s and was there when Angelas recorded the song.
