I read somewhere that Napoleon is the most sung-about folk hero/villain with over 50 songs about him.

Here is BONAPARTE'S LAMENT or NAPOLEON ON THE ISLE OF ST HELENA

Oh Boney he has gone from his wars and his fighting
He has gone to a land he can take no delight in
He may sit him down and tell of the battles he’s been in
While forlorn he may mourn on the Isle of St. Helena.

And Louisa she do weep from her husband departed
She dreams when she sleeps and she wakes broken-hearted
Not a friend to console, and no one to turn to
But she mourns when she thinks of the Isle of St. Helena.

Oh ye gentlemen of great wealth beware of ambition
For some twist of fate could soon change your condition
Be steadfast in time, for what’s to come you know not
And your days they may end on the Isle of St. Helena.

The wild rushing waves round our rocks they are washing
And the high billows heave round our shores they are dashing
He may look to the moon, to that great Mount Diana
While alone he do mourn on the Isle of St. Helena.

Ye Parliament of England and your Holy Alliance
To that prisoner of war you may now bid defiance
For your base intrigues, and your baser misdemeanours
Have caused him to die on the Isle of St. Helena.
