I remember George C. Scott singing a version of this in "Patton," or maybe it was "Final Days of Patton," if Eva above is right. It was on TV around 1984, since that's when I got my first VCR and recorded it as a test, and watched it a couple times. This is what I remember:

Oh Lilly, from Piccadilly
She is the blackout queen.
Lilly, from Piccadilly
Ugliest girl I've seen.

With searchlights playing overhead
Til Messerschmidts are gone,
Please don't take your mask off
You look much better with it on!

CHORUS:
Oh Lilly, from Piccadilly
She is the blackout queen!

[can't recall the other verses]
