I just learned, in another thread, that the only tune I've ever heard for this song
only goes back 50 years. This is the Waters tune, used by Joan Baez, by Art Thieme,
by everyone else I can remember hearing, and also used by Pete Seeger for I Come
And Stand.

Bruce O. writes above that it isn't easy to come by any tunes other than
the Waters tune. Is that still so? Are there any readily available recordings
to another tune?
