Thanks for refreshing my memory on several points of French grammar, Monique.   It's interesting to to me that even with the various suggestions of what it sounds like Rosie Clooney is singing in French, you can't 'hear' anything that makes sense even as slang.
That makes me wonder whether maybe Rosie was singing in some dialect such as Canadian French or Creole, or maybe her pronunciation wasn't very good.   : )



All we can really tell is that she's singing about singing and about dancing in the meadow.
