You Ain't Goin' Nowhere - guitar chords and comments
Lyrics without distraction HERE
Dylan didn't officially cut this himself until US "Greatest Hits Vol.2" (1975), and then with pleasing assistanse from Happy Traum. Three more unreleased famous songs got the same treatment during the same September recording session: "I Shall Be Released", "Tomorrow Is a Long Time" and "Down in the Flood" (Crash on the Levee).
The song was written in Woodstock 1967, and first recorded in the basement studio of "Big Pink" - the house rented by members of the later "The Band". These recordings were going into the wild, and in '68 the Byrds grabbed it and made it a single hit.
The "lyrics" have been changed many times; of course also by Dylan. I use the Big Pink originals. I think you're free to alter them; even add your own nonsense. Nobody will sue you for that.
