I'm too late to be useful for the choir with which I sing, which I will be directing tonight because the actual director is ill, but I would like to see what 3-part repertoire anyone uses for this feast.

Another idea popped into my head, keeping in mind "future readers" : is there a thread already which contains compositions already submitted by composers on this forum for various feasts around the liturgical year? I know individual threads exist (since I've just bumped a couple), but is there a single clearinghouse?
