Eureka!

(But don't hold your breath waiting for me to provide music. I can hear this in my head, but I don't know any music).

Hail glorious Saint Patrick, dear saint of our isle,
On us, thy poor children, bestow a sweet smile:
And now thou art high in the mansions above,
On Erin's green valleys look down with thy love.

Hail, glorious Saint Patrick, thy words were once strong
Against Satan's wiles and a heretic throng;
Not less is thy might where in heaven thou art:
Oh, come to our aid, in our battle take part.

In the war against sin, in the fight for the faith,
Dear Saint, may thy children resist unto death:
May their strength be in meekness, in penance, in prayer,
Their banner the cross which they glory to bear.

Thy people, now exiles on many a shore
Shall love and revere thee till time is no more;
And the fire that thou hast kindled shall ever burn bright,
Its warmth undiminished, undying its light.

Ever bless and defend the sweet land of our birth,
Where the shamrock still blooms as when thou wert on earth,
And our hearts shall yet burn, wheresoever we roam,
For God and Saint Patrick, and our native home.
