I couldn't find the chords for this song anywhere, so I thought I'd put them up. I'm surprised I couldn't find this, maybe I have the name of the song wrong! Arlo Guthrie did a great cover of this song at Woodstock in 69. he played it with a 12 string so it may sound a little different. Chords might be wrong, but it sounds good to me. I play it with a capo on the second fret and it seems true to the version of the song I have, but it's Bobby, so it may change depending on which version you have. Standard tuning Capo II I'm walking down the line, I'm walking down the line, I'm walking down the line, My feet will be a'flyin', I'll tell you'bout my troubled mind. This pattern continues for the rest of the song.
