Jesus Christ is risen today Alleluia

I just merged the 8 hymnals with first line "Jesus Christ is risen today, Alleluia" (or "Hallelujah" in a couple instances) with the 391 instances of "Jesus Christ is risen today Our triumphant holy day". Six of the eight were clearly the same hymn save for the alleluias; unfortunately, after completing the operation I realized I hadn't kept notes of which two instances might conceivably not be the same hymn. Sorry.

But I think the chances are egregiously slim.
