Cautions to keep in mind: This was written in 1977 for the Vatican II rite only (notice that Mysterium Fidei and Quia Tuum are not used in a Tridentine Mass). However, the 3/3/3 structure in the Kyrie does exist here. And the original "Ite, Missa Est" selection (here with "nonconventional" added to title) does
not follow the convention of using same music for "Ite, Missa Est" and the immediately-following
"Deo Gratias", so that is provided for in "version 1" and "version 2" (each of them using part
of the original "nonconventional" version).
