There is at least one good recording of him doing his own songs. Also, Inti Illmani (my spelling can be creative, so this may be approximate) has done a number of his songs, and they tend to include words in their album jackets. I'll rummage and see what I can find. His widow, Joan Jara wrote a pretty good biography of him which I read some time ago. His work in theater and music in Chile was pretty amazing. From the songs it seems that he really spent time with working folks everywhere. He was killed in the coup in '73...Anyway, I'll see what I can find. I know that I can lay my hands on L'arado (the plough) as well as one song about him, probably "winds of the people" as well. I believe that Joan is still alive. Perhaps she could be persuaded to put together a book with words and music of his songs. They are still apt.
