There's another version of "Oyster Girl" that Brian Peters has recorded -- same story, but slightly different words. (One of which, in the last line, I couldn't figure out; asked Brian what it was and promptly LOST the sheet of paper I had written it on -- as well as my memory, of course.) And a third version, with Manchester, I think, instead of London as well as a slightly different storyline.

And another by The Boarding Party -- "The Shanghaied Dredger." (I can post the words if they're wanted.)
