What books did the congregation use during the service?
The aforementioned missal was available, but most people didn’t seem to be using anything – nor did they seem to be participating, but rather were "hearing mass", to use the old-fashioned expression.

What musical instruments were played?
The organ (probably the original four-manual Kilgen) was used only for one hymn. One of the church’s four choirs, the all-male schola cantorum, chanted pretty much everything in Latin from a choir loft. A couple of sopranos and altos joined them for the Byrd Ave Verum Corpus.

Did anything distract you?
I was distracted by the lessons for the day being chanted in Latin with no translation provided. I wondered if this congregation, even though accustomed to a Tridentine mass, actually knew what was being sung. A few small children made the noises that small children will make in church, but that didn’t compare with my annoyance at the lack of a proper service sheet.
