Sung by Vera Lynn, the sweetheart of the British soldiers of World War II. 3/20/1917 - 6/18/2020

Lyrics

When the lights go on again all over the world 

And the boys are home again all over the world 

And rain or snow is all that may fall from the skies above 

A kiss won't mean "goodbye" but "Hello to love"

When the lights go on again all over the world 

And the ships will sail again all over the world 

Then we'll have time for things like wedding rings and free hearts will sing 

When the lights go on again all over the world

When the lights go on again all over the world

This was a mid-WW2 song. The title refers to the practice of having to black out possible bombing targets and to avoid back-lighting targets for bombs.
