Sloppy Miserere

Saturday's Early Music Show on Radio 3 consisted of highlights from a concert given by the Cardinal's Music (director Andrew Carwood) which explored the music heard by the young Mozart when he was on his travels. This included, of course, the Allegri Miserere, which Mozart famously heard and wrote down. I was amazed to hear the choir performing, not a scholarly version of the work, but what sounded like the standard 20th century performing edition which confects 2 different version together and has an entirely non-canonical (but very effective) top C. Perhaps more information was given at the concert, but on Radio 3 listeners were led to believe that we were hearing what Mozart had. Which wasn't true at all.
