It's an informative site. I had almost forgotten this song; it's what Pete Seeger was singing in March, 1941:

Lyrics as reprinted ibid., p. 85.
ORIGINAL ISSUE: "SONGS FOR JOHN DOE" (ALMANAC RECORDS
, early May 1941 [PETE SEEGER, lead vocal]

It was on a Saturday night and the moon was shing bright
They passed the conscription bill
And the people they did say for many miles away
'Twas the President and his boys on Capitol Hill.

CHORUS:
Oh, Franklin Roosevelt told the people how he felt
We damned near believed what he said
He said, "I hate war, and so does Eleanor
But we won't be safe 'till everybody's dead."

When my poor old mother died I was sitting by her side
A-promising to war I'd never go.
But now I'm wearing khaki jeans and eating army beans
And I'm told that J. P. Morgan loves me so,

I have wandered o'er this land, a roaming working man
No clothes to wear and not much food to eat.
But now the government foots the bill
Gives me clothes and feeds me swill
Gets me shot and puts me underground six feet.

CHORUS

Why nothing can be wrong if it makes our country strong
We got to get tough to save democracy.
And though it may mean war
We must defend Singapore
This don't hurt you half as much as it hurts me.

Then in February, 1942, Pete was singing this:

Lyrics as recorded by THE ALMANAC SINGERS, New York, NY, c. Feb 1942, and reprinted ibid., p. 104 (Minor corrections by Manfred Helfert).

ORIGINAL ISSUE: "DEAR MR. PRESIDENT," Keynote K-305-A (KEYNOTE ALBUM 111), 1942. [PETE SEEGER, solo vocal]

Dear Mr. President, I sat me down
To send you greetings from my home town
And send you best wishes from all the friends I know
In Texas, Alabama, and Ohio and unaffiliated.

I'm an ordinary guy, worked most of my life
Sometime I'll settle down with my kids and wife
And I like to see a movie, or take a little drink
And I like being free to say what I think
Sorta runs in the family,
My grandpa crossed the ocean for the same reason.

Now, I hate Hitler, and I can tell you why
He's caused lots of good folks to suffer and die
He's got a way of shovin' folks around
I figger it's about time we slapped him down.
Give him a dose of his own medicine. Lead poison!

Now, Mr. President
We haven't always agreed in the past, I know
But that ain't at all important now
What is important is what we got to do
We got to lick Mr. Hitler, and until we do
Other things can wait.
In other words, first we've got a skunk to skin.

War means overtime, and higher prices
But we're all willing to make sacrifices
Hell, I'd even stop fightin' with my mother-in-law
Cause we need her too, to win the war, ol' battle-axe.

Now, as I think of our great land
With its cities, and towns, and farming land
With its so many good people a-working every day
I know it ain't perfect, but it will be someday
Just give us a little time.

In just eleven months, such a change of heart!
