The "Californio" business bugs me. Since it appears in the chorus, the implication is that on cue everybody would suddenly remember to switch from the "Mexico" pattern. Not bloody likely, mate.

My guess is that Hunt was either inadvertently mingling two distinct choral patterns or else absent-mindedly made a slip (or an "improvement") influenced by the "Californio" in "Sacramento."

In any case, I suspect that "Californio" entered all recorded post-Lomax versions of "Santy Anna" solely through "Sailor Dad" Hunt.

As for Lloyd & MacColl's source (if there was only one and if they didn't modify the tune slightly on their own), it may well have been Hugill himself. I tentatively suggested something similar in the "Blood-Red Roses" thread.

Long ago I used to assume like many others that Lloyd, MacColl, and others of the better-informed, stylistically conservative revivalists, had access to troves of fabulous traditional texts and tunes that had never been published. Now I know better. I doubt that L & M got anything from an oral source whom they didn't credit by name. In Lloyd's case, as we now know, not even the credited songs can be taken at face value as fully "traditional".
