There's a good bit of material available here already. May as well include both song groups, though they aren't related to each other beyond dealing with the same subject.

ADMIRAL BENBOW "Come all ye seamen bold..." (Set published by Cecil Sharp. It's based on the set he noted from Captain Lewis of Minehead in 1906, but has been altered and additional material added from an unspecified source. Two unidentified midis are provided, but neither is the tune published by Sharp.)

ADMIRAL BENBOW (2) "Come all you seamen bold..." (Copper Family set)

Lyr Req: Admiral Benbow lyrics "We sailed from Virginia..." -Several discussions combined, with historical notes, links to broadside editions and so on. Both DT files and the entry from the Traditional Ballad Index are also quoted.
