I have a kanaka song about kanakas used as pile drivers and voyaguers on the Columbia.

Also I should say Chinook jargon..couldn't rememberthe word..there was a Chinook regular language..I read in some bookthey were so traumatized by some epidemic they had before Lewis and Clark (not intentional via blankets etc.) that they lost their ability to speak in their own language. Chinook jargon of course is a language with words from many other languages. There were songs and prayers and books in it. Lots on internet. Katherine??? of B.C. has sung some songs with jargon in them..mg
