Traditional. This has been recorded by, at least in the folk circle, Pete Seeger, Bob Dylan, Joan Baez, Art Garfunkel, and John Denver. There are probably more than I'm missing. I have a verse that none of them include that I think is important. I moved its location from where it generally is in the poem to before the Mother/Father verses. Comments would be appreciated. :} EDIT: There's a weird buzzing sound. I have no idea what that is.
