Google doesn't seem to have it, though this story of the Cariboo Gold Rush may whet your appetite while I make time to type it out. I'd like to see the new lyrics (about globalisation) when you find them, please.
As it happens, I dug out the family copy of Philip J. Thomas's 1979 book _Songs of the Pacific Northwest_ two nights ago. Quite the Pacific NW folk renaissance going on right now: his album "Where the Fraser River Flows" has just been released on CD, and Hancock House is planning another edition of the book, perhaps this year. Jon Bartlett & Rita Ruebesaat have been making CDs of a selection of their radio recordings from the Schools Broadcasts in BC (also late 1970's) and even Buzz Martin, the singing logger, can now be heard online and on CD. All that, and your Chinuk Wawa project too...
