From a priest reader:
After long delay, we’ve introduced Our Lady of Guadalupe into our calendar as a Feast, but now we have a problem: finding chants and texts! What is done in your community for Mass (Ordinary form) and Office regarding the Feast proper? Our choirmaster is especially interested in what chants are used from the Graduale. If you are able to give some insight a quick response (December 12th is this week!!) would be much appreciated.
