I can do the chords, actually 2 different arrangements exist, the original, and also one by Barbara Dane and Judy Collins. But it will take me a while to find time to do it, sorry.
If you can get (and you can) the book Rise Up Singing, ed. Peter Blood & Annie Patterson, from any major bookstore or folkie instrument store, A) you should get it!!!! and B) if you don't get it, just take the chords from the song on page 61.
Anyway, glad you like the song! I'll get back ASAP.
