"Day Tripper" and "Lady Madonna"

Two days ago, I remembered something that I noticed about a year ago:  the guitar figures in "Day Tripper" and "Lady Madonna" have a certain similarity, not so much in terms of rhythm, but in the intervals.  It might be easier to illustrate this with tabs than with notation.

The guitar phrase in "Day Tripper" starts like:

D|---------2-0---4---0-2-|

A|-------2-----2---2-----|

E|-0-3-4-----------------|

And that in "Lady Madonna":

G|-----------------2-|

D|---------0-0-2~4---|

A|-0-0-3-4-----------|

Both figures start with the tonic note, followed by the minor third and then the major third.  In the tabs above, this appears as |-0-3-4-|.
