CAJUN ACCORDION DISCUSSION GROUP
There are at least two: Beausoleil on "Bayou Boogie," (Rounder 6015) and Bois Sec Ardoin w/Balfa Toujours on "Allons Danser" (Rounder 60810).
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
