The Oliver Cromwell Song
(from Monty Python sings)

The most interesting thing about King Charles the First is 
that he was five feet six inches tall at the start of his reign, 
but only four foot eight inches tall at the end of it. 

Because of...
Oliver Cromwell, Lord Protector of England
Puritan. 
Born in 1599 and died in 1658 (September) 
Was at first only MP for Huntingdon
But then he led the Ironside Cavalry at Marston Moor, in 1644 and won.
Then he founded the New Model Army 
And praise be! beat the Cavaliers at Naseby 
And the King fled up north like a bat! to the Scots.

But under the terms of John Pym's Solemn League and Covenant, 
the Scots handed King Charles the First, over to...

Oliver Cromwell, Lord Protector of England and his warts
Born in 1599 and died in 1658 (September)
But, alas! disagreement then broke out
Between the Presbyterian Parliament and the military 
who meant to have an Independent bent and so
The Second Civil War broke out
And the Roundhead ranks faced the Cavaliers at Preston, Lancs
And the King lost again, silly thing
(Stupid git)

And Cromwell sent Colonel Pride to purge the House of Commons of the 
Presbyterian Royalists, leaving behind only the Rump Parliament

Which appointed a High Court at Westminster Hall
To indict Charles the First of - tyranny 
Charles was sentenced to death, even though he refused to accept
That the court had - jurisdiction 
(Say goodbye to his head)

Poor King Charles laid his head on the block - January 1649 -
Down came the axe, and in the silence that followed 
The only sound that could be heard was the solitary giggle, of

Oliver Cromwell, Lord Protector of England
Born in 1599 and died in 1658 (September)
Then he smashed Ireland
Set up the Commonwealth and more
He crushed the Scots at Worcester, 
and beat the Dutch at sea in 1653 and then
He dissolved the Rump Parliament
And with Lambert's consent wrote the Instrument of Government
Under which Oliver was Protector at last.
