"Room Five Hundred and Four" is probably my favourite World War Two song

some other suggestions

"He Wears a Pair of Silver Wings"
"Tell Them We All Died Game" (from Australia)

and this one, in tribute to our American allies:

Thanks, Mr Roosevelt, its swell of you
For the way you're helping us to carry on
We'll see the British Empire smiling through
When at last these dark and stormy days have gone
And Frankin, by the way, please convey
Our congratulations to the folks in USA
We're saying thanks, Mr Roosevelt, we're proud of you
For the way you're helping us to carry on.
