Anyone has the music for the Lorica Sancti Patricii(episcopi armachiae)?

Well, I can give you links at the tunes "St. Patrick" and "Deirdre" which are the ones used in our hymnal, along with the directions for singing it.
Here is a link to the first tune, "St. Patrick" and the words for most of the verses. Please note that it says that the first half of the tune is sung for the first four lines then it starts over for the next full verse.

http://rockhay.tripod.com/worship/music/christbewithme.htmThen it goes back to "St. Patrick for the last verse.
The web site is not from my church, but the tunes and words are correct. At my parish we sing all the verses with great vigour. (There have been jokes in the choir about being at "St. Marks and All Verses")
