In the written notes for the boy-soprano Steven Mockel video, I have clarified the notes, indicating that I have my doubts as to the identification of the second soprano in that duet. I believe that my German information source might have been mistaken based upon the fact that Max Emanuel Cencic does perform in several other tracks in both the CD and DVD versions of the audio sources. He, however, is not listed for the duet, and the singer does not look like Cencic.
So, what prize should we give to the person who accurately identifies the actual singer?

Any clues? Any comments?
Also, I added the lyrics to the notes.
And, how about a prize for anyone who finds another vocal recording of Steven Mockel !
