Columbian (Bloomsburg, Pa) (Apr. 4, 1907) [ref. to the Civil War]:

They stopped the game of poker and joined the hungry pack
By rushing to the cook's wide open door.
Where the hardest of hard crackers were given, called "hard tack."
O, hard tack come again no more.

            CHORUS
'Twas the song and the sigh of the hungry,
Hard tack, hard tack, come again no more.
Many days you have lingered upon our stomachs sore.
O, hard tack come again no more.

He was a lazy hungry soldier, who cursed his life away--
His clothing showed their better days were o'er.
He sighed for mother's buscuits and pot pie far away.
O, hard tack come again no more.
       Chorus.

We crossed the hills and valleys, thro' briars, bogs, and brush,
And gray-backs were an ever-present bore.
We heard reb yells and vollies [sic], sometimes had ground-hog mush.
O, hard tack come again no more.
       Chorus.

Though very old and wormy, you were pie beside that mush
With our salt-horse and our pork forevermore.
If gray-backs made us squirmy, our hunger made us rush
For that hard tack that we never did adore.
       Chorus.
