Melody from the ODEF edition by Guyard & co (identical to Sandhofe), rsigns and neumes from H

Mattiacus + rsigns + slight melodic adjustment on DEUM: the Fa in this position is often an attraction of a primitive Mi.

Added quarterbar following crochu

Followed suisnera's advice (which is also mattiacus' opinion) on the word "ad" to be sung on Do.
