Ebbie,
Stay tuned for a lecture on where "sailors" went -- which could rarely be USA because "sailors" are British by default and why would they want to go to USA? Oh, and if they did, they would jump ship and join Mexico in a fight against the Stupid USA. But anyways, Sailors would go to the exotic Brazils and other fabulous international rios -- in which the Rs are pronounced like Hs! And Sailors would never sing songs that are just about, y'know, stuff that other people sing about who don't go to exotic Brazils sing about. In fact, Sailors have ("had") their own repertoire of songs that has nothing to do with other songs, cuz they're special. And because Stan Hugill the non-historian (but that doesn't matter, because he was a SAILOR so HE KNOWS through his DNA encoding) threw the idea in a book while his leg was broken and he was convalescing.


Or maybe people just sometimes read the spelling of foreign words/names and carelessly / uncaringly pronounce them according to the assumed spelling rules of their own language?
