The Bahamian "The Captain Go Ashore" was recorded by Frederick McQueen, Andros Bahamas. And also by the Boat Band ("Take Me over the Tide, Harbourtown casette, 1990, to be reissued on CD May 1 2009 hint hint).
This is one of the shanties mentioned by Dana in "Two years before the mast", as being sung on American ships in thne 1850's. Hugill(introduction to "Shanties of the Seven Seas") thought the song was lost, but luckily Fwederick McQueen(and the Boat Band!) knew otherwise.
