I remember watching John Hartford pick the banjo and guitar on the old Glen Campbell show as a kid. The running gag on the show was that John never really spoke, he just let his music do the talking. Sometime around 1980 or so I went to see him at the old Guthrie Theater with some friends. He sang this song that night. It's been one of my very favorites ever since, and it takes on more poignancy with each passing year. You youngsters can check out a David Mayfield tribute cover here, and a Gregory Alan Isakov version here.
