Here’s wonderful musician Walter Mouton playing Chere tout tout (no, not My tout tout by Rockin’ Sidney).  The sound is a little rough, but this guy’s only recordings are one 45rpm and two tracks on the Les Blanc movie soundtrack J’Ai Ete Au Bal (I Went to the Dance).  Don’t recognize the venue, though there’s lots of older couples out on the floor.  The notes add Wayne Toups and Jackie Cailler, but I don’t see them onstage.  That’s likely his regular band, with Junior Martin on pedal steel.  Compare to this photo of Mouton in 2008 with Joel Savoy on fiddle.
