Here are some details of the traditional Latin Mass celebrated by Archbishop Alexander Sample, from Rorate Caeli. Therein you'll find the various ministers, choirs, etc. I attended that Mass. A traffic accident on the beltway caused me to be late, but I did arrive just before the Gloria.
EWTN broadcast it live, and produced the recording below. I'm impressed that they got it uploaded to youtube so quickly. The Archbishop's sermon begins at the 54:28 mark; it's definitely worth several repetitions.
