You can download the Communion Chant for the 4th Sunday of Lent (Year C). Its opening phrase calls to mind the authentic version. I have created a rehearsal video to assist volunteer choirs.
“A much greater source of anxiety to Us is the style of action of those who maintain that liturgical worship should shed its sacred character, who foolishly say we should substitute for sacred items & furnishings ordinary common things in daily use.” —Pope Saint Paul VI (14 Oct 1968)
