Not necessarily better than the originals, but, I like these covers:

Concrete Blond--Everybody Knows
Odetta--Times they are a Changin
A couple of oldies which come to mind, the first of which is an instrumental:

"Harlem Nocturne" -- The Viscounts' unique interpretation of an old jazz standard.

"You Can't Catch Me" -- The Blues Project's cover of a Chuck Berry song, on their "Projections" album. Which version is better is debatable, of course, but I prefer this one.  I also prefer it to a version the Rolling Stones had on one of their early albums.

Projections was a great album.  Nice call, Al!
