Some people in Europe think that Jolie Blonde is the hymne of Cajun Country.
So it must be an essential.
Most cajun songbooks for fiddle or accordion content often the same songs.
When starting most people see these songs as essentials.
When people play longer they discovered there own essentials.
It's depending of what they like.
Depends on the perspective, I have known people who were glad when their jolie fille left for another, maybe felt a little sorry for the other guy. And like the song says, she aint the only one in this world.
