Not on my list, but I do Like "Martha My Dear". It has an real old-fashion 1920ish or so type sound.
I read only recently that George wrote Savoy Truffle after a box of chocolates (i.e. cream tangerine). Only the Beatles could pull something like that off.
Martha was Paul's dog, and supposedly the part about "hold your head up you silly girl look what you've done...when you find yourself in the thick of it....is a veiled reference to Martha having "an accident" inside the house.
"Io sono stanco, sono imbigliato, and I wan't everyone here to know, there ain't gonna be no trouble from me..Don Corleone..Cicc' a port!"
