“My Country, ’tis of thee,
Sweet land of liberty,
Of thee I sing.
Land where my fathers died,
Land of the pilgrims’ pride,
O’er every mountainside
Let freedom ring.”

(And then a bunch more verses, all, I believe, written by a former minister at the church where I sing in Newton, MA.)

The other one, as you discovered, is “The Battle Cry of Freedom”, and yeah.

I don’t usually need no steenkin’ soundtrack albums, but in our family the Civil War tape lived in the car for at least ten years (and is probably still there if my mom remembered to transfer it to the Prius), and it was always the one that stayed in the player longest and most often.
