El Sombrero Blanco (the music) is on Youtube. Google it. And it is playing in the background in My Darling Clementine when Henry Fonda is playing cards in the saloon and Doc Holliday walks in, about 22 minutes into the movie. Coming from Southern California, I love that old Spanish music.   By the way, the 1940 version of the Zorro movie is "The MARK of Zorro", not the Mask.
