CAJUN ACCORDION DISCUSSION GROUP
If this is the song you mean, it's done by the Ardoin Brothers with Canray Fontenot. That's Gustave "Bud" Ardoin on accordion and vocal. I bet that's Lawrence Ardoin on drums and Morris Ardoin on guitar. http://www.npmusic.org/Ardoin_Brothers_and_Canray_Fontenot_Dimanche_Apres_Midi.mp3
