Cassandra Wilson (earthy, lyrics in English):

Trio Mocoto (melody played on Cuica, which is nuts):
As an aside, I recently heard on the radio a cover of this by Art Garfunkel, which may be one of the worst things I've heard. As you may expect, he mananged to strip all of the life out of the song, which made me sad.
