Interesting sman. He actually sings the aria in the same key. Leads me to believe he knows more than he's saying. It's not a lucky guess. Maybe he has perfect pitch. If so, he should ditch that ugly persona and get into a good music school. There's work for countertenors but not ones looking like him.
This might surprise you. Although he could use help with his intonation, it's better than Angela's. Her pitch is absolutely deplorable....at least in this cut.
