" Travailler c’est trop dur" is the Cajun song the most known in France. In 1975 or 76 it was an enormous success. With Zachary Richard, Beausoleil and Balfa Brothers, it was the beginning of the revival of the Cajun music in France, on returning to the USA, in Europe and in the World.

Thanks to both Jon and Marc for the info. I thought this was a somewhat obscure song, but not so...I've found several interesting versions, including Julien Clerc, Polo Hofer, Michael von der Heide...and Marc and the Boiled Crawfish from Sweden! World Music, indeed!
