Cajun lyrics when translated are often very similar.
Amede Ardoin seems to tell the same story in just about every other song he recorded, and Iry Lejeune too, to some extent.
Tunes could and were used for more than one song as well.
It all gets very confusing, dont it?
I can see no similarities between Lacassine Sp & Jongle A Moi though.
Roj, why try to copy Emmylou when there are other more authentic versions to learn from?
If its Cajun Fiddle you want, Iry LeJeune is the last place I would look. He did play fiddle, but was known for accordion.
Try listening instead to stuff from Balfa Bros, Dennis McGee, Leo Soileau, Lawrence Walker, Wade Fruge et al.
Note that these are CAJUN fiddlers, not to be confused with country, appalachian, bluegrass or any other lesser style :-)
And dont get hung up on lyrics. Everybody just sang their own, and some of 'em spoke very bad French, Cajun or otherwise.
(Iry was accused of that by many, see Ann Savoys book. If ya aint gottit, gettit!)
