Tantum Ergo Sacramentum at Mater Ecclesiae

After finishing one church gig, I scrambled down to Mater Ecclesiae to catch whatever was left of the Vesperal Mass. A most remarkable thing happened at the end of the procession, something I should have foreseen (and therefore had my camera ready to go) but didn't. When we got to the altar of repose, the choir began Tantum Ergo in harmony, and the people joined in spontaneously--from memory. All of them. I captured as much of it as I could. Sometimes the most "ordinary" music is the most extraordinary.
