After years of wanting to, I finally went to the Cajun and Creole Folklore Archives at ULL. As I expected, it is a treasure trove of video, got several videos of my dad playing at the Liberty with Ed Deshotels, quite a bit of my great grandfather, along with a pile of other stuff. If anyone other than me has been interested in the audio files of Barry Ancelet's book "Cajun and Creole Folktales", it's there. Watching an old video now of Ed Poullard playing with Canray Fontenot.
Go visit Chris Segura at the archives and bring your check book. It's all digitized and you can search individuals or topics.
I'd like to go see that some day. There's a similar initiative that has been going on here in Nova Scotia. We had an old priest, Père Anselme Chiasson who died about 10 years ago at about 91 years old. For a period of about 40 years, during the 50s, 60s & 70s, he went into Acadian villages and recorded the old folks telling stories and singing their traditional songs. There is a project that was going on in Chéticamp, (an Acadian village in Cape Breton, Nova Scotia) to put all this material together and catalog it.
Try to listen to the interview with Austin Pitre around 1965 (conducted by Ralph Rinzler) where he explains some different dances, including the difference between a one step and a two step. I could have spent a month going through their stuff!
