While in London I am staying at St. Bede’s in Clapham Park. The older, Extraordinary Use of the Roman Rite, has been offered for some years. Occasionally they have a very fine vocal group provide polyphonic music for the Sunday Mass.
It was a fitting way to celebrate the Feast of the Exaltation of the Cross, the first anniversary of Summorum Pontificum coming into effect.
Here is the Sanctus, Consecration and Benedictus
This is from Wm. Byrd’s Mass for Four Voices.
