Having seen some (not a huge amount, though) of TBD and other songs on youtube and the likes, but never in person, I'd still be glad to hear something different when these songs come up. If he plays this or any other song this way if I ever get the chance to see him live, I'd love it.
But like Vere said, for some people the way you've always heard it on the record is the way you should hear it live so...all in all, I'd be okay with hearing either version--I'm happy as long as the man keeps playing any gigs
