AN OLD IRISH HYMN

Some say the lyrics of this hymn go back to the time of Patrick - fifth century Ireland - or perhaps later - to the eighth century - but the melody we now sing is certainly more modern. Does anyone know more about when the melody was invented? Whatever the accurate times of the melody, this is one of the older hymns of the Christian faith. I hope you enjoy it as much as do I.

(These words vary a bit from the video, but you'll get the idea.)
Be Thou my vision, O Lord of my heart;
Naught be all else to me, save that Thou art.
Thou my best thought, by day or by night,
Waking or sleeping, Thy presence my light.
2. Be Thou my Wisdom, Thou my true Word;
I ever with Thee, Thou with me, Lord;
Thou my great Father, I thy true son;
Thou in me dwelling, and I with Thee one.
3. Riches I heed not, nor man's empty praise,
Thou mine inheritance, now and always:
Thou and Thou only, first in my heart,
High King of heaven, my Treasure Thou art.
4. High King of heaven, my victory won,
May I reach heaven's joys, O bright heav'ns Son!
Heart of my own heart, whatever befall,
Still be my vision, O ruler of all.
