HeaveHo USMMS Song

Heave Ho! My Lads! Heave Ho!
Words and Music by Lieut. (jg) Jack Lawrence, USMS, 1943.

Give us the oil, give us the gas
Give us the shells, give us the guns.
We'll be the ones to see them thru.
Give us the tanks, give us the planes.
Give us the parts, give us a ship.
Give us a hip hoo-ray!
And we'll be on our way.
 
CHORUS
Heave Ho! My Lads, Heave Ho!
It's a long, long way to go.
It's a long, long pull with our hatches full,
Braving the wind, braving the sea,
Fighting the treacherous foe;
Heave Ho! My lads, Heave Ho!
Let the sea roll high or low,
We can cross any ocean, sail any river.
Give us the goods and we'll deliver,
Damn the submarine!
We're the men of the Merchant Marine!
