Hi; I got this version out of an old school music book, that was from the California State Department of Education, Sacramento, 1958. Says the song was 'Adapted by W. S. Williams'.

"Who's that knocking at my door? Who's that knocking at my door?
Who's that knocking at my door?"
Cried the fair young maiden.
"It's me myself and nobody else," cried Barnacle Bill the sailor.
"It's me myself and nobody else," cried Barnacle Bill the sailor.

"I'll come down and let you in,
I'll come down and let you in,
I'll come down and let you in,"
Cried the fair young maiden.
"I'm me myself and nobody else," cried Barnacle Bill the sailor.
"I'm me myself and nobody else," cried Barnacle Bill the sailor.


and exactly how it's written' unless I made a typo I didn't catch..

Hope this is what you're for! :-) (ewww that looks funny), Becky
