In addition to the Shanties there were other tunes that were heard on the sailing ships of yore.
Dan Worrall in his book "The Anglo-German Concertina", under the heading: "Types of music played on concertinas at sea" mentions forebitters such as "Tom Bowling",popular songs such as "Loreana", and Hymns as "The Old Rugged Cross". And there was dancing; the most famous "Jack's the Lad" which has become known as the "Sailor's Hornpipe".
On another thread some eminent Mudcatters have been authenticating shanties. I would like to propose trying to collect other music.
Cheers,
