I've not watched 'The Wire' either El, nor 'Thor', and I don't follow the 'Star Trek' films. I might have caught 'The Jungle Book' you mention, caught one halfway through not so long ago, but don't know if it's the one you are talking about.
Countertenor is quite high for a male singer isn't it
It is probable that it was that adaptation of "The Jungle Book" you saw in part as that was the Disney "live action" remake of their animated film, both have been shown on television more than once in recent years. There was a British 1942 adaptation which might have been shown. That adaptation was in colour, was the definitive version until eclipsed by the Disney animated film - it didn't have any songs in.
gorgeous voice and can reach quite high notes -loved this
Countertenor is the highest male singing voice and fairly rare. There were a lot more men with that voice back in the days when women weren't allowed to sing on stage, just men and boys. At that time they were called castratos - I think you can guess as to why.
Falsetto voice may sound as if at similar range of notes as a countertenor but clearly sounds like a false voice rather than natural,
