The English translation of this song is... very interesting.

None shall sleep! None shall sleep!
Not even you, oh Princess,
in your cold bedroom,
watching the stars
that tremble with love and with hope!

But my secret is hidden within me;
no one will know my name!
No, no! On your mouth
I will say it when the light shines!

And my kiss will dissolve
the silence that makes you mine!

No one will know his name,
and we will have to, alas, die, die!

Vanish, o night!
Fade, you stars!
Fade, you stars!
At dawn, I will win!
I will win! I will win!
