Random lines remembered from a very long time ago:

The Ark Valley Boys started off as above with

Who's that knocking at my door? (3x)
Cried the fair young maiden

It's only me, from over the sea
Cried Barnacle Bill the sailor
I'm all lit up like a Christmas tree
Cried Barnacle Bill the sailor

And somewhere after

I drink(s?) me whiskey when I can
Whiskey from an old tin can
For whiskey is the Life o' man
Cried Barnacle Bill the sailor

I'll come down and let you in (3x)
Cried the fair young maiden

Well hurry down 'for I bust in the door
Cried Barnacle Bill the sailor

etc.

Sorry I can only dredge up fragments, but after all I was only 4 or 5 years old then. I'm not sure of the order of the verses, and I'm sure there were some additional ones I don't recall. The verses were connected to make something of a narrative, with a "suggestive" but not offensive (even to 1940's Bible Belt rednecks) conclusion.

My recollection was that the "fair young maiden" verses were nearly all in the format of

"some short phrase" x3
Cried the fair young maiden

The "Barnacle Bill" verses were generally more or less full four stanzas. After all - it's his song, so she played "straight man" to him.
