I think this song has entered into the American Canon, and I don't think any particular expertise in Cajun music or pronunciation is needed to sing it. This is one of those songs that everybody knows at least part of it, so it's fun to sing it with a group or with an audience.
Recipes, by the way, are in this thread (click). I shouldn't be writing about this when I'm hungry. Jambalaya and beer sounds really good right now.
