Here is another song from WW2 I like.

We'll Meet Again

We'll meet again
Don't know where
Don't know when
But I know we'll  meet again some sunny day

Keep smilin' thru
Just like you
Always do
Til the blueskies drive the dark clouds
Far away

So will you please say hello
to the folks that I know
Tell'em I won't be long
They'll be happy to know
that as you saw me go
I was singing this song

We'll meet again
Don't know where
Don't know when
But I know we'll meet again some sunny day.
