BTW that song is called "Wellermen" and it is a traditional Antipodean (Australian/New Zealand) whaling shanty of unknown authorship. A Wellerman was a supply ship, and the most important supplies were tea, sugar and rum. I am from Australia and New Zealand (dual nationality) and in this part of the World a "Billy" is a makeshift tea kettle, often made from a large, old tin can.

These days billys are sold in camping supply stores etc, although sometimes people still make them out of 1/2 gallon spaghetti tins and bits of old fencing wire.

After all that, here are the lyrics...

There once was a ship that put to sea,
And the name of that ship was the Billy o' Tea
The winds blew hard, her bow dipped down,
Blow, me bully boys, blow!

Chorus (after each verse):
(HUH!)
Soon may the Wellerman come
to bring us sugar and tea and rum.
One day, when the tonguing' is done,
We'll take our leave and go.

She had not been two weeks from shore
When down on her a right whale bore.
The captain called all hands and swore
He'd take that whale in tow.

{Chorus}

Before the boat had hit the water
The whale's tail came up and caught her.
All hands to the side, harpooned and fought her,
When she dived down below.

{Chorus}

No line was cut, no whale was freed,
An' the captain's mind was not on greed!
But he belonged to the Whaleman's creed
She took that ship in tow

{Chorus}

For forty days or even more,
the line went slack then tight once more,
All boats were lost, there were only four
and still that whale did go.

{Chorus}

As far as I've heard, the fight's still on,
The line's not cut, and the whale's not gone!
The Wellerman makes his regular call
to encourage the captain, crew and all!

{Chorus x2 til Finish}
