15th century carol about the battle. Back when folk music was cool and not just for beardos and middle aged virgins.
Deo gratias Anglia redde pro victoria!
Owre Kynge went forth to Normandy
With grace and myght of chyvalry
Ther God for hym wrought mervelusly;
Wherefore Englonde may call and cry
Deo gratias Anglia redde pro victoria.
He sette sege, forsothe to say,
To Harflu towne with ryal aray;
That toune he wan and made afray
That Fraunce shal rewe tyl domesday.
Then went hym forth, owre king comely,
In Agincourt feld he faught manly;
Throw grace of God most marvelsuly,
He had both feld and victory.
Ther lordys, erles and barone
Were slayne and taken and that full soon,
Ans summe were broght into Lundone
With joye and blisse and gret renone.
Almighty God he keep owre kynge,
His peple, and alle his well-wyllynge,
And give them grace wythoute endyng;
Then may we call and savely syng:
Im pretty sure you sing it to the tune of "Mighty Mouse".
