Words seem better in poetry or song when emanating from the heart. You’re likely not old enough to remember WW II. This song then was about soldiers separated from their love. The only thing different for me it is about me separated from my Raquel.
We’ll meet again
Don’t know where
Don’t know when
But I know we’ll meet again some sunny day
Keep smiling through
Just like you always do
‘Till the blue skies drive the dark clouds far away
We’ll be together again…..
