This was the song my grandfather used to sing to me as kid. He used to sing it with his army buddies during World War II.

A Warrior Bold

In days of old, when knights were bold,
And barons held their sway,
A warrior bold, with spurs of gold,
Sang merrily his lay;
Sang merrily his lay:
"My love is young and fair,
My love hath golden hair,
And eyes so blue, and heart so true,
That none with her compare.
So what care I tho' death be nigh,
I'll live for love or die.
So what care I, tho' death be nigh,
I'll live for love or die."

So this brave knight, in armor bright,
Went gayly to the fray;
He fought the fight, but ere the night,
His soul had pass'd away,
His soul had pass'd away.
The plighted ring he wore
Was crush'd and wet with gore,
Yet ere he died, he bravely cried,
"I've kept the vow I swore.
So what care I tho' death be nigh,
I've fought for love and die,
So what care I, tho' death be nigh,
I've fought for love, for love I die
I've fought for love,
For love, for love I die."
