Mac has a clip of the Marian anthem at the end of today's Missa Cantata, which is as it is. People hear what they want to hear.
What is good is that the very small children at Mass, even those not singing will grow up hearing this music. That's down to their parents teaching them the chants. The Missa Cantata is merely the opportunity to sing what they already know.
Being as it's Lent it's time to crack open The Matthew Passion.
