Strange death of john doe

I'll sing you a song and it's not very long.
It's about a young man who never did wrong
Suddenly he died one day.
The reason why, no one would say.

He was tall and long and his arms were strong,
And this is the strange part of my song
He was always well from foot to head,
And then one day they found him dead.

They found him dead so I've been told,
His eyes were closed, his heart was cold
Only one clue to why he died -
A bayonet sticking in his side.
