Politically Incorrect Singing

In the Capitol Rotunda ceremony for Regan's Lying-In-State, the Air Force choral group the Singing Sergeants sang America the Beautiful including the usually banned second verse (which they sang as a fourth verse):

O beautiful for pilgrim feet
Whose stern, impassioned stress
A thoroughfare for freedom beat
Across the wilderness!
America! America!
God mend thine every flaw,
Confirm thy soul in self-control,
Thy liberty in law!
