Jamás podréis arrebatarme el cielo

Take my love, take my land
Take me where I cannot stand
I don't care, I'm still free
You can't take the sky from me
Take me out to the black
Tell 'em I ain't comin' back
Burn the land and boil the sea
You can't take the sky from me
There's no place I can be
Since I found Serenity
But you can't take the sky from me...
