Bert Lloyd called it 'Proud Land of Spain' and sang it in this form (probably one of his own re-makes):

THE GIRL WITH THE LOVELY BROWN HAIR
As I went out one evening
To view the dark meadows in spring,
It was down by the banks of the river,
I heard a young girl softly sing.

Oh, the moon it shone so brightly
And white was the gown that she wore;
She appeared like the Queen of the Indies,
Did the girl with the lovely brown hair.

I found she was backed like a salmon
And breasted just like a swan;
And the night that I spent in her arms, oh me boys,
I wished it was seven years long.

Next morning she said, "I've another
My bed and my fortune to share,
So fare you well, me young lover",
Said the girl with the lovely brown hair.

So I went down to the harbour,
Signed on a ship for the proud land of Spain;
All the sailors were singing and dancing
But I had a heart full of pain.
