Several important songbooks of the 'California Days' seem never to have been reprinted, and are not on line. Only parts of the content have been printed in Lingenfelter, etc. etc. The verses look like the sort of material found in books like these.

Two of these are John A. Stone's Put's Original Californa Songster, 4th ed, 1868, and his Pacific Songbook of 1861. Both are about 64 pp.
Joe, I recommend them to you for purchase. Only about $300 a copy in readable condition. You could bill Mudcat.....
