Here’s the late, great Aldus Roger and the Lafayette Playboys performing Allons á Lafayette at the 1994 Cajun French Music Association.  It’s the first commercially-released Cajun song, recorded by Cleoma Breaux and Joe Falcon.  Roger’s not singing, and neither is his pedal steel guitarist, so I’m thinking it’s the drummer. “Let’s go to Lafayette and change your name,” i.e., get married.  This is one of the most recorded songs in the Cajun repertoire.
