This one regularly pops up in sessions around here:

THREE MEN FROM BRISTOL

(each line should be sung twice, first by the lead singer and then by everyone together, before proceeding to the next line.)

There were three men from Bristol City
(repeat)
They stole a ship, and went to sea.
(repeat, and so on . . .)

There was Gorging Jack and Guzzling Jimmy
And also Little Boy Billee.

They took three packets of Arnotts Biscuits
And one large bottle of Drambuie

But when they reached the broad Atlantic
They'd nothing left, but one split pea.

Says Gorging Jack to Guzzling Jimmy
"There's nothing to eat, so I'm gonna eat thee."

Says Guzzling Jimmy "I'm old and toughish.
So let's eat Little Boy Billee."

"Oh, Little Boy Billee, we're going to kill and eatcha.
So undo the top button, of your little . . chemise."

"Oh may I say my catechism,
That my dear Mother taught to me."

He's climbed up to the main top gallant
And there he fell . . upon his knee.

But when he reached the Eleventh Commandment
He cried "Yo Ho! for land I see!"

"I see Jerusalem! . . and Madagascar!
And North and South Amerikay!"

"I see the British fleet at anchor!.
And Admiral Nelson, . . K.C.B. !"

They hung Gorging Jack, and Guzzling Jimmy,
But they made an Admiral out of little boy Billee.
