The guy is really good. That said, I wanted to point out that being able to sing high notes, around soprano range, it is an ability that is not at all rare for guys. In fact, it is not so much ability as it is skill, a vocal technique known as falsetto.
That is true but most of the highest male voices in their falsetto voices are not usually a soprano. There are not as many male voices that can reach the soprano range. Most high male voices reach the tenor range and that sounds very high on most guys. The musical range starts with baritone, bass, tenor, alto, then soprano.
From Wikipedia:
"In most cases, male alto voices eventually crack and become tenor, baritone, bass-baritone, or bass voices. Some men, on the other hand, have permanent alto voices."
Males who can still sing in the alto voice when they are adults are called countertenors. One famous countertenor is Freddy Mercury of Queen. We all know how high his voice was and he was still not a soprano. So the fact that this guy can sing Soprano (a Celine Dion song no doubt), even if it's in his falsetto, is quite a feat.
Here's the info I was reading on Wikipedia:
Countertenors
