Joan Baez’s version is the one I was most familiar with, because it was on the radio when I was a child. Later, when MTV came along, I saw The Band clip with Levon Helm singing lead. They’re both great. EDIT: holy smokes, I assumed it was an old folk song, possibly even Civil War era. It was written by Robbie Robertson! Oh my. It sounds so genuine and real, if you know what I mean. Gah.
