This was apparently recorded at a small venue in 2003. It is said to be the last recorded performance of Johnny Cash. At this point he'd recorded a few Dylan songs. This one seems to be written atop "Don't Think Twice, It's Alright."
I doubt Dylan would begrudge Johnny Cash pilfering a few chords and bars. But that's not what this clip is about. It's the chance to watch the last recorded performance of the Man in Black.
