If you ever get a chance to visit Eunice, you really should plan to visit the Liberty Theater on Saturday night where they feature the "Rendez-vous Des Cajuns" music show. Each Saturday different Cajun bands are featured. The show is broadcast on the local public radio and TV. I believe you can listen to the show by visiting http://www.krvs.org/
We saw Geno Delafose and the French Rockin Boogie Band... a grammy nominated Cajun band that was absolutely fantastic. The theater has a dance floor in the front and people just had a wonderful time. The show runs from 6 -7:30 every Saturday. You can buy tickets, but seats are available first come first serve. It didn't really matter though because most of the people were enjoying dancing so they didn't stay seated.
While we were there, there was a Cycle Zydeco group. They are a group of bicylists touring the Acadiana area. For four days they cycle through Cajun country and visit local tourist attractions. They were dancing and having a wonderful time.
