John: Bustin's older lyric comes from one Neville's five verses, as republished by James Hall (aka: Oliver Oldschool.) I don't believe we've recovered the "original-original" just yet. See above at: 06 Jan 23 - 12:26AM. Again, there was never any music to go with. Your call if that's a song or a short story with/about a song.

fwiw: The only vessel mentioned in Neville/Hall is Mike Fink's Mary. Supposed to be a keelboat but, there are no surviving drawings or plans of her and she's not mentioned anywhere in the lyrics. Assuming she, and he, was ever really real to begin with that is.
