I don't have that one but I have lots of Victor Jara songs. A while ago I translated Luchin for someone but can't now find it.
Here's Canto Libre instead:
A A7 A El verso es una paloma que busca donde anida estalla y abre sus allas para volar y volar
A E D A E Mi canto es un canto libre que se quiere regalar A quien estreche su mano a quien quiere disparar
A E Mi canto es una cadena sin comienzo ni final
A E D A E y en cada eslabón se encuentra el canto de los demás
sigamos cantando juntos a toda la humanidad que el canto es una paloma que vuela para encontrar estalla y abre sus alas para volar y volar
My words are a dove looking for a place to nest exploding, spreading its wings to fly and fly and fly
My song is a free song It wants to give itself to anyone who holds out a hand to anyone who wants to shoot.
My song is a chain without beginning or end and in every link you'll find the song of all the other people
Let's go on singing together to everyone on earth sing that the song is a dove flying, reaching out exploding, spreading its wings to fly and fly and fly.
(chords are from memory as I've broken 3 strings . . . )
