I am not sure, speaking as an ex-Merchant Navy man and a certificated Able Seaman that laundering Sea shanties too much is a good idea. I suppose for young chidren o.k. anything to protect the young, but Bowdler and his ilk have been my enemies all my life. I was at sea in the mid 60s and served in a small ship around the coast of Europe in between longer ocean going trips, we had to ocasionally bring large 40 gallon oil drums on board using what was known as "Norwegian steam" ie by hand power. We had a deck hand called Bert Grey from Shetland who acted as Shantyman and it worked brilliantly. He, and we, used Shanties for real (Sally Racket for short haul and Whup Jamboree( a very non-PC version) and very enlightening it was too. NB I don't know if it's the same in the Americas, but among Limeys a lot of things acquire National names. Norwegian steam, Irish pennants etc. curious, any one throw light?
