John Brown's Body is a marching song often sung by the Union in the Civil War, which you'd probably recognize if you heard the tune. The lyrics go as follows:
"John Brown's body lies a mouldering in the grave
John Brown's body lies a mouldering in the grave
John Brown's body lies a mouldering in the grave
His soul is marching on!
Glory Glory Hallelujah!
Glory Glory Hallelujah!
Glory Glory Hallelujah!
His soul is marching on!"

The Battle Cry of Freedom is another song from the Civil War sung by the Union. The lyrics are near identical to the ones at the end of this song:
"Yes we'll rally round the flag, boys, we'll rally once again,
Shouting the battle cry of freedom,
We will rally from the hillside, we'll gather from the plain,
Shouting the battle cry of freedom!"
"John Brown's body lies a mouldering in the grave John Brown's body lies a mouldering in the grave John Brown's body lies a mouldering in the grave His soul is marching on! Glory Glory Hallelujah! Glory Glory Hallelujah! Glory Glory Hallelujah! His soul is marching on!"
Sound familiar?
"Yes we'll rally round the flag, boys, we'll rally once again, Shouting the battle cry of freedom, We will rally from the hillside, we'll gather from the plain, Shouting the battle cry of freedom!"
