I've looked for a little while now, but I can't seem to find the soundtrack tracklisting anywhere. I'm particularly interested in the opening credits song, and the song shortly after he comes to america, while he's lying in bed.. Sounds like a mexican elliot smith.
lol, you've got a point there, that site does list Besame Mucho as by Consuelo. I never noticed.
However, i think the version in the film may still be as listed above (it seems to depend what site you go on, for instance, if you search for it on say itunes, it's listed on the original motion picture soundtrack as Besame Mucho Artist : Joselo Rangel & Laura D'ita. This site below also has it listed as them)
