Here it is. Edit: I posted one from the wrong book. I have an older, public-domain edition which is apparently also not what Casavant Organist needs. Sorry I couldn't be of more help.
Either way, I might have not explained myself clearly. Sorry, irishtenor, it's not quite what I'm looking for, as I'm looking for accompaniment for the "Flectamus" verses. See Incardation's post for the verses to which I'm looking for.
