This biography of Phil Ochs was a little more respectful of Phil than the other one I read by Marc Eliot (I think the only other one that really exists, besides a bio-bibliography, which isn't the same thing). It also had a somewhat better writing style.
Not only is this a great book about an even greater man, but it's also a book that really helped me to understand the 1960s better. I think Phil really typified the era, and unfortunately, he also became a symbol of the whole disintegration of the movement.
I love you, Phil... to answer the question you posed to your brother: yes, your songs have survived, and they are as relevant as ever.
