I've always loved that song, especially as done by Hadley Fontenot in the Balfa recordings. I found the B part pretty quick but spent a long time on a very small part of that A part. Dewey's singing in that song still gives me frissons.
I love this song. Suzy Thompson wrote alternate lyrics to it for a friend's wedding and called it "Valse du Mariage". The California Cajun Orchestra recorded it on their first CD.
When my wife and I got married, Danny, Eric and Suzy played our wedding reception. We had them play "Valse Du Mariage" as our first dance.
