The B side of this 10" record, if I recall correctly, was called "Somewhere in England", and one of the verses, and its chorus, with a different tune to 'Colonel Bogey', went:

Dear Mum & Dad, It's been sometime since we've had
A chance to write to you with all this trouble brewing
But here is a line just to say that we are fine
And let you know just where we are, and what we're doing.

We're somewhere in England, somewhere on its British Isle
Doing our duty, with a song and a joke and a smile
We're somewhere in England, waiting for the work to begin
and it won't be long before you hear this song
From somewhere in Berlin.

      . . .    and the end of the last verse is something like:

And while we're away every hour of every day
We hope and pray that you will keep the home fires burning
