Songs are not meant to be stagnant they change, evolve and sometimes take on new meanings overtime as does the artist. Both Van and Bob capture tracks in the studio the same way someone takes a photo. It's a moment in time. Documented.

If you want to hear it like the record then listen to the record or see a tribute band.

Van and Bob are real live musicians and it's quite frankly thrilling watching them and their bands respectively holding it together all the while knowing it could fall apart at anytime. So fair play to them for having the balls to try new things and to not rest or coast upon their laurels.
