Well, it looks like Stewie has found the correct answer and thanks for that! Yes, the fragment of the tape is from the armpit version however.... I am sure that Dylan sings the whole song and that he stuck to a traditional version (the Stewie version matches every lyric perfectly) in his early days. (Remember this is pre-Guthrie (at least for Bob), pre-Denver, pre-Jesse Fuller, pre-Tony Glover.) Bob has just arrived in Minnesota and is just starting out. (Big hint at how early: no harmonica!)

Thank you all again so much,

Simon
