On Sundays at my home parish in my native, St. Agnes in St. Paul, MN, the hour of Vespers has been sung in Gregorian Chant, using the Liber Usualis, at 3 pm for some 40 years… at least. Vespers followed by Benediction of the Blessed Sacrament. Every Sunday.
Sometime during the 90’s the pastor, Msgr. Richard Schuler, a well-known Church musician back in the day, dusted of a chanted version of the Divine Praises for after Benediction which he had written in 1953. They… we… have been singing the Divine Praises ever since.
I was at St. Agnes on Sunday and I caught this recording. The chief cantor, Paul LeVoir, had made a spiffy PDF of the notation, which I share hereunder.
