ORBIS CATHOLICVS has a photo report up on the Pontifical Mass of Cardinal Castrillon Hoyos in St. Ivo alla Sapienza by Borromini. He tells us that the Mass setting was Palestrina's Missa Regina Coeli. Just a couple of photos:
We are informed one of the Canons of the Cathedral of Milan served in a liturgical capacity, and members of the Oratory, the Canons Regular of the New Jerusalem, the Norbertines, and even the SSPX in Rome, were present at the Mass.
