CES, I need your help!

Hi, CES. In your response on Mao and the sunsets, you gave a tiny snippet of a poem "Mao- la villa de los bellos atardeceres..." and my wife, a Spanish major and a new Mao fanatic, would really appreciate if you could tell us how to find a copy of the poem or who wrote it. We have such fond memories of Mao and the poem would be perfect to put in our travel memory book. Thanks!
