It's actually fine in French--I've sung it with several groups.   I've also found an English paraphrase (not literal, thank goodness)--that rhymes. But it's still clunky. Your best bet is French.

The site I found it at claims the tune is Provencal-- 13 th century.

At any rate it handily pre-dates the Bizet use of it in a farandole in L'Arlesienne.
