he titles the song, Do You Sing Any Dylan?

But he also writes (a propos his songs in general, not particularly this one),

"Also, the more observant amongst you might notice that there are probably a few words different here and there from my original recorded version. This is called the folk process. Please don't e-mail me and ask me why I changed them. In many cases, in the recording studio, the words in my head often didn't come out of my mouth, and I was too lazy, too pushed for time, or too broke to go back and insert the proper words, probably all three. In any case, most fitted well enough, and some were actually an improvement on the original lyrics."
