What is it about this Bob Dylan Song?...

...My Back Pages, which makes guitar virtuosos want to cover it. On the new Eric Johnson album, Bloom (I don't have it yet, but I soon will), Johnson covers it (see video).

And previously, Carl Verheyen, another favorite of mine, covered it on his album Garage Sale. Verheyen's version is truer to Dylan's original. Johnson's version, while cool, turns it into a real uptempo piece, which the original wasn't.
