Lyrics:

There will soon be an end to this cold and wicked war
When those hard-headed communists get what they're looking for
Only one thing that will stop them and their ferocious fun
If General MacArthur drops the atomic bomb
Now over in Korea our boys have fought and fell
But they died just like heroes, so many shot and killed
They had their hands tied behind them and were murdered by the score
By those dirty-minded Communists who started this sad war

There'll be fire dust and metal flying all around
And the radioactivity will burn them to the ground
If there's any commies left they'll be all on the run
If General MacArthur drops the atomic bomb

Old hard-headed Joe will be feelin' mighty blue
When he finds out he's bitten off more than he can chew
For the thrashing will be ended and the job will be well done
If General MacArthur drops the atomic bomb

Ol' MacArthur has the power to stop those [?]
And he'll make them sorry for their underhanded schemes
Just leave it to the general for he really has the nerve
To give those no good communists just what they deserve

There'll be fire dust and metal flying all around
And the radioactivity will burn them to the ground
If there's any commies left they'll be all on the run
If General MacArthur drops the atomic bomb
