Andy Williams sang this - folky or what? :-)

The harbor lights were shining,
The moon was at its high.
The captain said, "Thank God we're home!
We've drunk the barrels dry."
The mizzen mast was shaken,
And the lanterns all burned low,
I'd never thought we'd make it
But we've twenty leagues to go
So blow you southern trades
And guide me safely to the shore,
I'll never ever gonna sail
The seven seas no more

(etc.)
