I don't know anything about all that chord language y'all are discussing, but I do know there are at least 2 different positions to play it on the accordion, and I guess a few slightly different versions of each. On a C accordion, I play it in either Am or Dm.
And then, there's this, by my mentor, Harrison Fontenot. Link #2
Dan Franceski tried to decode it 2005. He started in 4/4 and shifted to 5/4 for the 3rd and 9th measures! If 13 measures is correct, then he's missing two beats somewhere.
In the Balfa Brothers fiddle version, it is played in G major. The chords are G, Bb and D. In the accordion version, it is in Am. The chords being Am, C and G. The Mamou Playboys blended the two songs by starting off the fiddle version in G, then coming in at the end on the accordion in G minor using a Bb accordion.
There seem to be many more versions of this song than the famous Balfa rendition.
Lots of different melodies, chords, major, minor, you name it. Website #1.
Thanks for posting. Never saw or heard this one.
Another version with a different melody line, and in Am. (with a funny D chord at the end)
There are no "correct" basses to sustain the melody, and no guitar backing also, and still it sounds OK. Another great job by Chris!!
