Here's the version from Pete's Where Have All the Flowers Gone songbook.

Bring 'em Home
(Pete Seeger, 1966)

So if you love your Uncle Sam
Bring 'em home, bring 'em home.
Support our boys in Vietnam,
Bring 'em home, bring 'em home.

It'll make our generals sad, I know,
Bring 'em home, bring 'em home.
They want to tangle with the foe,
Bring 'em home, bring 'em home.

They want to test their weaponry,
Bring 'em home, bring 'em home.
But here is their big fallacy,
Bring 'em home, bring 'em home.

Our foe is hunger and ignorance,
Bring 'em home, bring 'em home.
You can't beat that with bombs and guns,
Bring 'em home, bring 'em home.

I may be right, I may be wrong,
Bring 'em home, bring 'em home.
But I got a right to sing this song,
Bring 'em home, bring 'em home.

There's one thing I must confess,
Bring 'em home, bring 'em home.
I'm not really a pacifist,
Bring 'em home, bring 'em home.

If an army invaded this land of mine,
Bring 'em home, bring 'em home.
You'd find me out on the firing line,
Bring 'em home, bring 'em home.

Even if they brought their planes to bomb,
Bring 'em home, bring 'em home.
Though they brought helicopters and napalm,
Bring 'em home, bring 'em home.

Show those generals their fallacy:
Bring 'em home, bring 'em home.
They don't have the right weaponry,
Bring 'em home, bring 'em home.

For defense you need common sense,
Bring 'em home, bring 'em home.
They don't have the right armaments,
Bring 'em home, bring 'em home.

The world needs teachers, books and schools,
Bring 'em home, bring 'em home.
And learning a few universal rules,
Bring 'em home, bring 'em home.

So if you love your Uncle Sam
Bring 'em home, bring 'em home.
Support our boys in Vietnam,
Bring 'em home, bring 'em home.
