Hang out the washing on the Siegfried Line

We're going to hang out the washing on the Siegfried Line,
Have you any dirty washing, mother dear?
We're going to hang out the washing on the Siegfried Line,
'Cos the washing day is here. 

Whether the weather may be wet or fine
We'll just rub along without a care.
We're going to hang out the washing on the Siegfried Line,
If that Siegfried Line's still there. 

Mother dear, I’m writing you from somewhere in France,
Hoping this finds you well.
Sergeant says I’m doing fine, a soldier and a half
Here’s a song that we all sing, this'll make you laugh:

We’re going to hang out the washing on the Siegfried Line,
Have you any dirty washing, mother dear?
We’re going to hang out the washing on the Siegfried Line,
‘Cos the washing day is here. 

Whether the weather may be wet or fine
We’ll just rub along without a care.
We’re going to hang out the washing on the Siegfried Line,
If that Siegfried Line's still there.
