I have no access to the video at the link. Is it this one? If so, you have the lyrics here and the story illustrated here.
I couldn't find any data online. In one of my songbooks it reads "refrain d'étudiants" which more or less means "back of the bus song". This one doesn't sound like a Louisiana song to me and my mom now in her mid-eighties would sing it when I was a child.
