I have been watching videos of Shakespeare's plays, and here is a clip from a particularly well done movie version of Henry V:
This is the St. Crispian's day speech, just before the battle of Agincort, which is considered to be the greatest battle in English history. This speech is also where the "band of brothers" line originated from.
If only Bush could be given "a muse of fire".
This next clip is sort of a movie promo, but it has the hymn "Non nobis" from the play, which is sung after the battle:
The hymn in Latin is
Non nobis domine, non nobis, sed nomini tuo da gloriam
Not unto us, O Lord, not unto us, but unto Thee give glory
Which is taken from Psalm 113:9 (KJV)/115:1 (LXX)

Next, I hope to see the Lawrence Olivier version from 1944:
