Celia Cruz - "Guantanamera"

Here's information about the song "Guantamera" from http://en.wikipedia.org/wiki/Guantanamera

'' 'Guantanamera' ("girl from Guantánamo") is perhaps the best known Cuban song and that country's most noted patriotic song.

The original lyrics to the song, as written by José Fernández, relate to a particular woman from Guantánamo, with whom he had a romantic relationship, and who — if the lyrics are to be believed — eventually left him. ...

Given the song's musical structure, which fits A-B-A-B (sometimes A-B-B-A) octosyllabic verses, the Guantanamera lent itself from the beginning to impromptu verses, improvised on the spot, similar to what happens with the Mexican folk classic La Bamba. Fernández's first use of the song was precisely this; he would comment on daily events on his radio program by adapting them to the song's melody, and then using the song as a show closer. Through this use, the Guantanamera became a popular vehicle for romantic, patriotic, humorous, or social commentary lyrics, in Cuba and elsewhere in the Spanish speaking world...

The better known "official" lyrics are based on the first stanza of the first poem of the collection "Versos Sencillos" (Simple Verses) by Cuban nationalist poet and independence hero José Martí, as adapted by Julián Orbón. Word has it that Orbón considered Martí's poems as fitting, and thus dignifying, to such a popular song. Given Martí's significance to the Cuban people, the use of his poem in the song virtually elevated it to unofficial anthem status in the country."
