Various spellings and titles were given to many cajun songs, as cajun was not a written language taught in schools. Quite the reverse in fact, cajun was at that time banned in school, kids would get beat for even speaking it in the playground. Amedee Breaux first recorded this song, believed to have been written by his sister Cleoma (as Ma Blonde Est Partie). She played guitar, her other brother Ophy on violin and Joe Falcon on triangle. Joe later married Cleoma and they became the first to actually record cajun music on April 27th 1928 (Allons a Lafayette + The Waltz That Carried Me To My Grave) Joe on accordion, Cleoma on guitar and vocals.
Amedee Breaux recorded Ma Blonde Est Partie in Atlanta April 1929.
In many of the early recordings the titles of songs, and even the musicians names would quite often be mis-spelled owing to language diferences and the "relaxed" attitude of performers and recordists.
So you can spell "Jolie" and "Blonde" any ways ya like, hon. Makes no difrense ta ma old ears :-)
