I wasn't born in the war time yet there are several songs from war world 2 always catch my heart whenever I hear them.  Let me put down the lyrics for you.  I am sure that you can search them on internet and listen to these beautiful work of music.

White Cliffs Of Dover

There'll be bluebirds over
The white cliffs of Dover
Tomorrow, just you wait and see.

There'll be love and laughter
And peace ever after
Tomorrow, when the world is free.
 
The shepherd will tend his sheep
The valley will bloom again
and Jimmy will go to sleep
in his own little room again.

There'll be bluebirds over
The white cliffs of Dover
Tomorrow, just you wait and see.
