Guest-

Without a fragment, or the recording, I can't even speculate about BM's missing verse.

They do seem to be taking liberties, rewriting, with a fine old shanty and even misusing some of the sailor jargon such as "gonna slip my cable" which literally means unfastening the anchor line (sometimes bueying it) from the ship for a speedy get-away but usually means as sland that the a sailor has died.

Cheerily,
