If you haven't seen it, seek out the DVD of 'Jai ete au bal: Roots of Cajun and Zydeco Music', a film by Les Blank, Chris Strachwitz and Maureen Gosling [Brazos Films DVD BF-103]. The DVD includes 30 minutes of previously unreleased bonus footage. Features Chenier, Balfas, Nathan Abshire, Doucet, Hackberry Ramblers, Delafose etc etc.
First rate!
