For the sake of discussion, it's best to post lyrics if we don't have them. these lyrics are from the site McGrath cited.
Hmmm. I have to say I don't know the tune to "On Sunday I Walk Out with a soldier."

I DON'T WANT TO JOIN THE ARMY
Tune: 'On Sunday I walk out with a soldier'

I don't want to join the army,
I don't want to go to war.
I'd rather hang around Piccadilly underground,
Living off the earnings of a lady typist.
I don't want a bayonet in my belly,
I don't want my bollocks shot away.
I'd rather stay in England, in merry merry England,
And fornicate this bleeding life away.
