You have taken Quire Cleveland's recording of this piece and added a score for people to sing along. That's an enjoyable thing for people to do, but unfortunately, in this case and in Byrd's Ave verum (and maybe others), you have incorrectly given Jameson Marvin as the conductor. He was guest conductor of Quire Cleveland for our Palestrina program, but not for other pieces on our channel. You should correct what you can and be more careful in your future labeling.
