Why didn't Jon play the guitar on Wanted at Endicott, but did here, less than two weeks later?

Somehow, I think Jon sounded better there as well (at least a bit less whispery) - especially on the "I drive all night..." part HE ALMOST SOUNDED LIKE HIMSELF AGAIN! Unfortunately, the choruses still need some work.
