I couldn't find this in DT. It is from Ewan MacColl's 'The Manchester Angel'.

ROUND CAPE HORN
Ewan MacColl

Our ship, she lay in harbour
A ship of noted fame
She lay in Plymouth harbour
The 'Conway' was her name
She's waiting there for orders
To take her far from home
Proceeding on a voyage
Around the north Cape Horn

As we was a-laying off the sound
A-rigging of the sails
We cleared old Plymouth harbour
And showed the land our tail
From ship to ship they cheered us
As we went sailing on
Proceeding on a voyage
Around the north Cape Horn

Now as we had been a-sailing
Some five months and four days
We sighted Valparaiso
And anchored in the bay
Them Spanish girls come aboard of us
I solemnly declare
They're far beyond your English girls
With their knobby heads of hair

They're far beyond your English girls
Who on you will impose
For when your money is all spent
They'll pawn and sell your clothes
They're far beyond your English girls
For they're both kind and true
For when your money it is all spent
Some more they'll give to you

Farewell to Valparaiso
Farewell, then, for a while
Farewell to yonder green mountains
Farewell to yonder green isle
And when our ship, she gets paid off
We'll certain sing a song
God bless them little Spanish girls
We left around Cape Horn
