Spaw, thanks for posting the lyrics. That link above doesn't take you to them any more.

The lyrics as sung on the recording I have (from a WWII Songs album) are just a tad different in a couple places.

PRAISE THE LORD AND PASS THE AMMUNITION
(Words and Music by Frank Loesser
Music by James Sanderson)

Down went the gunner, a bullet was his fate.
Down went the gunner, and then the gunner's mate.
Up jumped the sky pilot, gave the boys a look,
And manned the gun himself as he laid aside The Book,
shouting:

"Praise The Lord and pass the ammunition!
Praise The Lord and pass the ammunition!
Praise The Lord and pass the ammunition and we'll all stay free!

Praise The Lord, and swing into position -
Can't afford to be a politician!
[Can't afford to sit around a-wishin']
Praise The Lord! We're all between perdition
And the deep blue sea!"

Yes, the sky pilot said it, You've got to give him credit
For a son-of-a-son-of-a-gun to run free,
Shouting:

"Praise The Lord, we're on a mighty mission!
All aboard! We're all a-goin' fishin'!
Praise The Lord and pass the ammunition
And we'll all stay free."
