Here's one I learned from some Breton schoolboys about 50 years ago.

Par les champs et par les plaines
S'en allant deux compagnons, compagnons
Qui chantaient ‡ perdre haleine,
Que la vie avait su bon, du bon!
Wui chataient ‡ perdre haleine,
Que la vie avait du bon!!


There was a good deal more to the story but my tattention span was short back then and I never learned it! :D

Trans:

Over fields and over meadows
Two companions go along, go along,
Singing loud enough to lose their voices
How good life is, how good life is.
