This 1986 Nicholas Spitzer movie is worth a look and listen. Some old style Creole/Zydeco music, some amazing vision of some of the greats of the genre. Raw ( originally shot in 16mm ) and a little dated, but this 45 min. video is full of nostalgia and interest.

Thanks for posting. My parents are from Opelousas and this brought back memories. Was actually a member of the Inseparable Friends Benevolent Society,
