"Abstracts of Folklore Studies" cites the the same mag, crediting Lloyd and adding "Shanty used at tops'l halyards and other jobs."

The "New Grove Dictionary of Music and Musicians" (1980) informs us that "Some shanties are modal; among the modes used are the Myxolydian (e.g. Haul Away for Rosie) and Dorian (e.g. Bring ‘em Down)," implying that Lloyd's "Bring 'em Down" had some substantial existence.

Steeleye Span recorded it, which is substantial enough for me. ; ]
