Thanks to all that prayed for my choir, we ended up doing fine except for a small train wreck near the end. We ended together on the right pitches which generally leaves the congregation with the impression that you did it correctly… at least I hope. Start well, end well and people will probably forgive you for what’s in the middle.
Connected Tidbit: did you know the Vatican II documents encourage the use of chant and sacred polyphony in the Mass. Tell that to someone next time
