Mick Pierce, an interesting site. Many of the post-1850 songs.

Of the ten songs on the cover of "Canciones del Pais de California," nine are printed with sheet music, etc., in "Music of Early California;" only "La Culpa" is missing (other title?- there are several Latin American songs with that title or a title including those words).

Most of the material at the sheet music site is not Californio, but post-statehood, after the Americano takeover.
