“Cheechoko’s Dream” song

A misspelled Jargon word is a clue to some missing songs…
I found “Cheechoko‘s Dream” and “Cheechoko‘s Song” both mentioned in a college thesis completed a few months ago.
No luck yet finding a copy of the songbook it was published in. Anyone have really good library access during the Covid crunch?
The subject of the study, by the way, is The Mountaineers, a post-frontier club founded in 1906 Seattle — thus the easy analogies between “cheechakos” and (obviously Settler) mountain-climbing enthusiasts.
