search web under "BBC - WW2 People's War - Lights out in London in 1943 ".
check under the heading Blackout for reference to the song.
This is a great story Janis.
At dusk the blackout blinds and curtains were drawn so that enemy aircraft pilots were not aided in navigation by the lights from below. For that reason there were no lamp lights, no neon lights on buildings, no lights at railway stations, nor on the trains or buses - no lights on anywhere. Have you heard the wartime song, `When the lights go on in London all over the town'? At that time it was hard to imagine. Most of us carried a small torch pointed down when we were out after dark. There were air raid precaution wardens on the streets who, on seeing a light, would shout loudly "Put out that light".

I did some researching and found this:
When the Lights Go Up In London - Hubert Gregg
I'm going to get lit up when the lights go up in London;
I'm going to get lit up as I've never been before.
You will find me on the tiles;
You will find me wreathed in smiles;
I'm going to get lit up - I'll be visible for miles!
The city will set up when the lights go up in London;
We'll all be lit up as the Strand was, only more, much more
And before the party's played out;
They will fetch the fire brigade out
To the littest uppist scene you ever saw!
HERE we go. This is an excerpt and you can also download it. I just sent it to Margaret and her sister.
