Having spent many years singing and playing Cajun music, I can assure you that many "musicians" take a shot at singing Cajun lyrics. If the singer did not grow up "Cajun", they will probably butcher the language pretty badly, and end up singing a bunch of nonsense.

One of the best sources the lyrics is the liner notes from any Steve Riley album. He has spent a lot of time and effort to present them in a form accesible to the average person.

Also, many of these songs have different versions with different lyrics.

Not to mention that many phrases and words from Cajun French are colloquil (local corruptions) expressions. Like Jamaican English, it is not easily understood.

the word Catin in Cajun lingo means sweetheart.   Jolie Catin means pretty sweetheart.   Like Jolie Blonde means pretty blonde.

I have consulted three (3) French nationals, one of the a language instructor. I got them to listen to some Cajun and Zydeco tunes for purposes of interpreation. All three of them said they could only understand a fraction of the words.

So... it is best to find an old version, by the original artist, of a song that you want to learn and work real hard on it, and then you will possibly sound like a Cajun.

Another really good source is Ann Savoy's book of songs and lyrics.
And the big yellow book, Ye Yaille Cher.

Again... try Steve Rily and the Mamou Playboys albums. That way you get the song and the lyrics.

Bien Merci!
