They're sailing on England
Oh, what a shame!
Someone is after our island again!
We'll let them have it
Oh, yes, we will!
But maybe they won't want it
When they get the bill!
For we wrote the story
Of the old brigades.
We know the glory
Of yesterday's parades!
We'll sell them Blighty
Yard by yard!
They'll buy it from the old Home Guard
They will!
They'll buy it from the old Home Guard!
EDIT: Yours isn't even about D-Day, is it? Now I feel silly.
