Bernard Shaw - Atomic Split.

What a terrible thing to do,
Man has split the atom in two.
For peaceful purposes so we are told,
Medical wonders to unfold.
Then came the war in thirty-nine,
Man committed a terrible crime.
He built a bomb, of course Atomic,
Man's love for man, is ironic.
Two Cities, Hiroshima and Nagasaki by name,
Were obliterated much to man's shame.
This was the war to end all wars.

What a terrible thing to do,
We have built a laser or two.
For peaceful purposes so we are told,
Medical wonders to unfold.
We now have nineteen hundred and eighty-five,
Are we lucky to be alive.
The next war will be in space,
What will become of the Human race.

What a terrible thing do to,
We have built a space ship or two.
For peaceful purposes so we are told,
Man's old dream will now unfold.
We have met some aliens from outer space,
What a terrible thing to do,
Now we have killed an alien or two.
Human Race let me say Adieu,
For now I know what will become of you.

Bernard Shaw
