I have an old Topic LP "Sea Songs and Shanties". with A.L. LLOYD, STAN KELLY. THE WATERSONS, EWAN MACCOLL, ALF EDWARDS, IAN CAMPBELL, DAVE SWARBRICK, HARRY CORBETT and others. One Track 4, Side 1 "The Plains of Mexica" by the WATERSONS, the liner notes explain thusly: "Shanties are usually sung prettied up in the folk song clubs, with tightly organised choruses and a musical discipline quite at odds with the rough and tumble work song, ship-board origins of these songs. The Watersons' sing an ocean going shanty in an ocean going way, roughly with plenty guts. This particular song, "The Plains of Mexico" is a version of "Bay of Mexico". I may be wrong but they sound quite similar, Someone correct me if I'm wrong. Anyway it's interesting to hear the ""real" version.....Arse and all....
