Not a love song—I guess you could classify this as an antiwar song. At any rate, its point of view is unique in my experience: not so much dwelling on the horrors of war, as on the difficulty of taking sides:

(THE FATHERLAND, THE MOTHERLAND) THE LAND OF MY BEST GIRL.
Words, Ballard Macdonald. Music, Harry Carroll.
New York: Shapiro, Bernstein & Co., 1914.

1. I'm blue thru and thru,
And I don't know what to do.
In my heart a battle's raging,
All my sympathies engaging.
My mother comes from sunny France; my daddy, from Berlin;
And just across the Channel lies the land my girl lives in.

CHORUS: There's the Fatherland, the Motherland,
And the land of my best girl.
They're all calling me,
And I love the three,
But make up my mind, I can't,
For in my heart's a triple entente
That beats for one, and beats for all,
Till my poor head's awhirl
Over the Fatherland, the Motherland,
And the land of my best girl.

2. By day and by night,
All the allies rage their fight,
'Gainst my heart their forces sending,
Gen'ral Love its fort defending.
On one side waves red, white and blue; on one, red, white and black;
And yet another side displays the proud old "Union Jack."
