Cajun music brunch within an hour of BR?

I know these exist out there, but I have a couple stipulations -- I have some people in town who have helped me out a lot this weekend, and I'd like to take them to a brunch with Cajun or Zydeco music. They're not the type of people to get up and go out on the dancefloor, however -- is there somewhere good to eat that we can all sit back and watch a band play and other people dance without feeling any pressure to join in? Maybe in the Lafayette area? Thanks!
