I went from Bob Wills to Harry Choates to Leroy "Happy Fats" Le Blanc and his Rayne-bo Ramblers. Rayne is a small town just off interstate 10, smack dab in the middle of southern Louisiana and Cajun Country...sort of. Harry Choates is also from Rayne, though some biographicals list New Iberia as his birthplace.
Some pretty cool images from the 1930s in the video. This one is called "La Place Mon Coeur Desires" from 1937, and it's more of a waltz, which is what a lot of Cajun music is based on. At least until more modern times where the influence has expanded to include country and western, pop, Zydeco, the blues, and rock, to some extent.
That's not to say that early Cajun music wasn't influence by, or had influence on any of a number of genres. It's just that so much of the stuff from the '30s and '40s was predominantly dance music, and most of that was either waltz or swing.
I think the title translates to "A place [in] my heart's desire," but what little French I know doesn't get me very far.
