Doug aka Darkriver(?): understand first that there are no absolute words to any Cajun song because all Cajuns sing their own version of whatever, be it Jolie Blonde or Madame Sosthene, although you might say there are certain thought habits perticular to each song (possible exception: songs connected with personalities like Iry LeJeune or Dewey Balfa). I don't know what Michael Doucet sang, but here's some I learned some years ago, which may be close to his lyrics and can give you a foot in the door to understanding what words are different:

Oh, Madame Sosthene, mais donnez moi-z-Alida
C'est la seule que moi j'aim'rais, depuis d'l'age de quatorze ans
Voulez pas me la donner, j'vas faire serment de la voler
J'vas la passer par la fenetre, and ramener dans ma biroutte.

Hope this helps. Hope you understand it. Tracy Schwarz.
