As stated above, I dig love and I dig the song I Dig Love but I think I'll have to vote for I Dig Love since the other tunes are so strong.
As side story - when I first played ATMP for a friend and they heard I DIG LOVE they thought the second verse George was singing "I love dick." We laughed about it. Listen and see what you think. And even if George does love Dick it's probably Dick (Richard) Lester.
