This morning, I heard the Piccolo Lasso Choir, a children's choir, sing the Missa Brevis by Leo Delibes at Harrington Church, the official Latin Mass parish in Dublin.
Here is another recording done, obviously, by a different choir, of the Gloria.
Harrington Church has been recently renovated for the good. Here is one photo from the website.
