Hi- I am trying to find out something about the poet and songwriter Luis Martz, who wrote some of the words to "Adelita". Where can I find a biography of Martz? Who can tell me the circumstances under which he wrote the poem, "La Llorona"? This appears to be a serenade by a frustrated lover, and to have nothing to do with the "Weeping Woman" ghost story.

Can anyone help me?
