Here is the great Cajun accordionist and singer, Ray Abshire, performing with Balfa Toujours at the 2011 Festivals Acadiens et Créoles in Lafayette, LA.  From left: Courtney Granger (violin), Kevin Wimmer (violin), Ray Abshire (accordion), Christine Balfa (guitar) and Yvette Landry (bass).  And sorry, but don’t know the drummer.  Also don’t recognize the song, and it’s one of the smaller performance spaces, not the main stage or the heritage stage.
