When I asked the question the only songs I had in mind were George songs, Old Brown Shoe, I Want To Tell You, and Blue Jay Way. (My memory may be off with Old Brown Shoe.) It seems to me, off the top of my head, that George seemed to use diminished chords more than the others, at least early on. His songs usually seemed to have a darker more minor quality, and a diminished chord is three minor intervals piled on top of each other.
