A similar variant was collected in 1950 from Tom Cornealy of Halifax, Nova Scotia, and recorded by Helen Creighton (Rec. no. 1448, Loc. no. AR 5172 in Nova Scotia Archives and Record Management).
The YouTube video above features a much longer and different variant by Tony Archibald from Port St. Mary on the Isle of Man.
GEST notes: Since Tom Cornelly's name is so similar to Tom Cornealy's, it is possible both variants of this song were collected from the same singer, especially since the transcriber of Leach's recording is not positive about Tom Cornelly's location as signified by a question mark after St. Shott's.
Rio Grande do Sul (Great River of the South) is the southernmost state of Brazil. The state's entire east coast has two huge sandy peninsulas which make one giant sand beach, broken only by a single outlet called the Rio Grande, which allows entrance to navigable inland waters and several port cities. It has long been a favorite destination for sailors from around the world.
