"Colinda" is a relatively well known Cajun-Song, at least for being part of the soundtrack of the movie "The Big Easy" in a more or less Reggae-ized version by Zachary Richard. I do like the version by the Tail Gators but could not find it on the internet (but I have it at home, on vinyl). The song was made popular by the 1962 version of Rod Bernard, with its mix of French (Cajun) and English lyrics. There has been a recording of the song with English lyrics only, by Jimmy Davis, the man who allegedly wrote "You are my Sunshine", two-times Governor of Louisiana.
Originally, this seems to have been a song with French lyrics. The song is about a girl called "Colinda", the best one on the Bayou. Nevertheless, as scholarship has shown, it has formerly been a song about "Calinda", a dance of Afro-Americans in Haiti and elsewhere. So, initially, "Allons danser Colinda" has meant "Let us dance the Calinda" and not "Let us dance, Colinda". It has been "poped" later to the one and only theme of "boy and girl".
