One country song that I have adapted to cajun style is
"Silver Threads & Golden Needles"....can play it moderately
fast as 2 step or as waltz...in key of G.

D.L. Menard and Eddie Lejeune played Wildwood Flower complete with French lyrics.

Joe Falcon used to play East Virginia Blues (Catahoula Stomp), Going Down the Road Feeling Bad (J'Suis Parti Sus le Grand Chemin Tres Dissatisfe), Careless Love (L'Amour Indifferent), Just Because (Juste Parce Que), and Jimmie Rodgers tunes (Raise Your Window High). You could probably produce a whole series of songs based on Jimmie Rodgers melodies.

Thanks everybody.
