The hymn of the human rights movement around the world. Often covered, but no version I know of has reached the quality of Joan Baez’ crystal clear vocal performance.
Regular (Sacco) or Low G (Vanzetti)
A piece that I had on my list for a long time, brought to paper finally. Like all the really great melodies, it is very easy to play. The difficulty is finding an end to this endless loop. Maybe it is best to just slow down the last two bars.
