Well, there's a used one for $4.95 plus shipping at Powell's Books in Portland, Oregon. Their service leaves a bit to be desired and they don't always have in stock everything that's listed in their database - but they do have a huge selection of books. Amazon.com also has the book listed, as a "special order," which means that they may or may not be able to get it for you. I got my hopes up and ordered Sam Henry's Songs of the People from amazon, but they diappointed me.
Hope that helps. Happy hunting.
