Put me down for "Dig It" - now THAT's album filler, in my opinion. Followed closely by "Revolution 9" and "Don't Pass Me By."
As for Ringo's covers of Buck Owens and Carl Perkins, I have no problem with that. I do find it interesting that legend has it that Perkins was at one of the sessions where they covered a song of his. If it was "Matchbox", he obviously didn't correct the lyrics. Actually, I believe it was "Honey, Don't".
