My heart is with the Renaissance but there are times when it is impossible to resist the sweet charms of the classical era, and particularly Schubert seems to have it all together. This piece might have been standard repertoire at some point in history, but I've never actually heard this Salve Regina in any parish setting, though it appears easy for any choir that can manage four parts, and the music is immediately available here.
Here is a youtube that gives you a sense of it. I don't know the choir but think of how wonderful it would be to hear this following any communion.
