Loi bai hat = Phien ban Lien bang mien Bac =

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!

(Chorus)
The Union forever! Hurrah, boys, hurrah!
Down with the traitors, up with the stars;
While we rally round the flag, boys, rally once again,
Shouting the battle cry of freedom!
(Chorus)
We are springing to the call of our brothers gone before,
Shouting the battle cry of freedom!
And we'll fill our vacant ranks with a million freemen more,
Shouting the battle cry of freedom!

(Chorus)
We will welcome to our numbers the loyal, true and brave,
Shouting the battle cry of freedom!
And although they may be poor, not a man shall be a slave,
Shouting the battle cry of freedom!

(Chorus)
So we're springing to the call from the East and from the West,
Shouting the battle cry of Freedom; 
And we'll hurl the rebel crew from the land that we love best,
Shouting the battle cry of Freedom.

(Chorus)


= Phien ban Hiep bang mien Nam =
Our flag is proudly floating on the land and on the main,
Shout, shout the battle cry of Freedom!
Beneath it oft we've conquered, and we'll conquer oft again!
Shout, shout the battle cry of Freedom!

(Chorus)
Our Dixie forever! She's never at a loss!
Down with the eagle, and up with the cross
We'll rally 'round the Bonnie Flag, we'll rally once again,
Shout, shout the battle cry of Freedom!
(Chorus)
Our gallant boys have marched to the rolling of the drums.
Shout, shout the battle cry of Freedom!
And the leaders in charge cry out, "Come, boys, come!"
Shout, shout the battle cry of Freedom!

(Chorus)
They have laid down their lives on the bloody battle field.
Shout, shout the battle cry of Freedom!
Their motto is resistance – "To the tyrants never yield!"
Shout, shout the battle cry of Freedom!

(Chorus)
While our boys have responded and to the fields have gone.
Shout, shout the battle cry of Freedom!
Our noble women also have aided them at home.
Shout, shout the battle cry of Freedom!

(Chorus)


= Phien ban co đong cho chien dich tranh cu nam 1864 cua Lincoln =
For Lincoln va Johnson, hurrah, boys, hurrah!
Down with the rebellion and on with the war,
While we rally round the cause, boys, we'll rally in our might,
Singing the holy cause of freemen.
