The duo by Hank Williams Jr. and Jimmy C. Newman is somewhat like what i have given below. Williams repeats the following line in English. At two points in the song, Newman gives the following verses in French.

Why'd you go and leave me in big Mamou, you left me for another alone and so blue. Oh come back, please come back, come back and live with me in big Mamou (or something like that).

Oh s'en allez a Grand Mamou. Jolie monde, mais jolie fille, moi, j'connais j'merite pas ca. Oh, hah, hah, oh mignonne, oh mais moi j'm'en va moi tout seule a Grand Mamou.

Translation: Oh, going to big mamou. Pretty world/everything, pretty girl, I know I didn't deserve that. Oh ha ha, oh pretty (one), I'm heading alone to big mamou.
