In addition to Tommy Makem's version of The Liar previously posted, he and Liam Clancy have a slightly different version, which adds the following verses:

Now, when Cromwell came to Ireland long ago,
He didn't shed a drop of blood, ye know.
All the people started grievin',
When they heard that he was leavin'.
If I knew a bigger lie, I'd tell ye so.

With King Billy at the Boyne, I heard him call
On his followers to follow till they'd fall.
Then he said: We've donw quite ably,
And we'll cannonize young Paisley;
Then he upped and sang a verse on Derry's wall.

By the way, The Chad Mitchell Trio (remember them) have a different version titled The Great Historical Bum. There is about nine verses to it, but no chorus. Maybe some day, if it isn't already in the data base, I'll find the time to post the lyrics.
