What a musical delight at St. Thomas Aquinas for Corpus Christi today (oops, sorry, the Feast of the Body and Blood of Christ):
Josquin des Prez, Missa Pange lingua
Gregorian sequence Lauda Sion Salvatorem
William Byrd, Ave verum Corpus (motet)
O salutaris Hostia at the exposition of the Blessed Sacrament
Pange lingua (eight verses!) during the procession of the Blessed Sacrament
Holy God, we praise Thy Name (in four part harmony!) at the dismissal
