\addlyrics {
  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 coming _ 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 _ _ _
  You can't take the sky from me
