Google offers a translated (horribly) version of the Luis Martz song (same site that Escamillo took the original Spanish from in this thread). Enter Luis Martz in Google, and you will find the ingeb site in the list. Click on translation (this translation is NOT on the ingeb site, it is a googleized translation).
Nothing on Luis Martz except that he is from Tehuantepec, Oaxaca.
