I THOUGHT we had a thread on this song, but I couldn't find it last night (maybe because my wife stole my computer and I was stuck with a phone?). But yes, we have a very nice thread on the song, and I've crosslinked it at the top of this page. We included the song in the Rise Again Songbook, and here is the page on the song that I worked up to supplement the songbook.

I wasn't familiar with Nueva canción, so I got quite an education when I was researching the song for the songbook.
