In 1971 Bob Dylan had a good voice
Actually, I was thinking just the opposite!
Bob's an acquired taste. If you're in the mood for his rasping and straining, he's great. But if you have to listen to him directly after hearing a good singer...yeesh.
@scmerriam: looks like Dylan recorded this song just for Greatest Hits vol. II. The Band covered it and did a better job, IMHO.
