An old Mexican song, Guitarras, Lloren Guitarras., something like Guitars, Cry Oh Guitars. The music is fantastic and it seemed to me he wasn't singing about guitars at all.
Lyrics translation:
Guitarras, lloren guitarras,
Guitars, cry oh guitars
violines lloren igual;
violins you cry as well;
no dejen que yo me vaya
don't let me leave
con el silencio de su cantar.
with your song silenced.
Gritemos a pecho abierto
Let's yell with a full chest
un canto que haga temblar
a song to make tremble
al mundo que es el gran puerto
this world that is the great port
donde unos llegan y otros se van.
where some arrive and others go.
Ahora me toca a mí dejarlas,
Now it's my turn to leave you,
ahora me toca a mi marchar;
now it's my turn to part
guitarras, lloren guitarras
guitars, cry oh guitars
que ahí queda lleno de amor,
that there remains so full of love,
prendido de cada cuerda,
clinging to each string,
llorando a mares mi corazón.
crying oceans, my heart.
