"Fume Fume Fume Ta Cigarette" (Smoke, Smoke, Smoke That Cigarette) by Harrison Fontenot. And I don't think I saw "Cinquante Piastres" by Joe Warren Cormier mentioned here.
Harrison Fontenot recorded almost all the popular country songs of his day, not sure how many were put onto record, though. I love his Fume Ta Cigarette, and was one of the first songs I learned to play on accordion. Another great one of his is "May You Never Be Alone Like Me", which fits perfectly as a beautiful Cajun waltz.
