Ever since the appearance of Summorum Pontificum I've wondered if I ought to learn what's now called the "extraordinary form" of the Roman Rite Mass. My Latin is probably good enough, and I'm sure I could manage the singing with some practice.
I haven't bothered with it yet. It seems like the spirit of the letter would be not to worry about it until some "stable community" of the faithful requested it in some place where I was serving. I guess I kind of imagined that if this ever happened, I would have those who wanted it donate the few hundred dollars I guess I would need for a 1962 altar missal and a maniple. I bet I could find everything else I would need in a half decent novus ordo sacristy.
But maybe this is something I should learn on my own, just to keep up, so to speak, with the times.
