Victor Jara's words, smuggled out of the football stadium in Santiago Chile were:

Canto qué mal me sales cuando tengo que cantar espanto!
Espanto como el que vivo, como el que muero, espanto.
De verme entre tanto y tantos momentos del infinito
en que el silencio y el grito son las metas de este canto.
Lo que veo nunca vi, lo que he sentido y lo que siento
hará brotar el momento...

How hard it is to sing when I must sing of horror
Horror which I live, horror which I die.
Seeing myself among so much and so many moments of infinity
in which silence and screams are the end of my song.
What I see I have never seen. What I have felt and what I feel
will give birth to the moment...

That comes from page seventeen of this intriguing looking article about music and death.
