I was an exchange student in Chile in 95-96 and I sung this song for my chilean classmates as part of the graduation ceremony, half in english and half in spanish. No matter where I look, I can not find the rest of the lyrics in the translation that I learned. I don't remeber any of the verses, but I will put what I remember of the chorus below. If anyone knows the parts that I don't, please post or email me at aberogan@graa.net.
Los amigos son amigos y unidos siempre estan,
Los amigos nunca dejan a su hermano desmayar.
No es bueno destruir, terminar la amistad
Pues, La vida triste es sin los amigos.
Friends are friends forever, if the Lord's the lord of them,
And a friend will not say never, 'cause the welcome will not end.
Though it's hard to understand in the father's hands we know,
that a lifetime's not too long, to live as friend.
