A good song. I am sure you all know the parody that was popular in UK folk clubs in 1950s/60s. Not sure who adapted it, but probably of Irish origin.
Called JOIN THE BRITISH ARMY. Cannot remember it all.

When I was young I used to be
A fine a man as you'd ever see
The Prince of Wales he said to me
Join the British Army

Too ra loo ra looraloo
Looking at monkeys up in the zoo
And if I had a face like you
I'd join the British Army
