Walter was singing about songs that ended on the draw on the ten keuy single row accordion,as being old. songs that were either in the dorian mode or ending on the dominant chord.
Of course songs that were in the mixolydian mode, flat7 [ equally old] he couldnt have played on his box , So walters analysis is incorrect,.
And I love her, written by lennon and macartney, is also in the Dorian mode , not old but old sounding, BUT still not traditional or old. Walter WAS a fine singer but was out of his depth on determining what was old.
