Some years back, someone posted a video of 4 people standing beside each other, each singing a different passage of the same song, to demonstrate the different varieties of highest men’s voices. It wasn’t a montage, they were definitely in the same room.
Can anybody dig up this video, or remember posting it? It seemed iconic and very useful, but for the life of me I cannot work the search-fu to find it.
I was surprised that there have been any castratos recently enough to actually be in a video. Wiki says Alessandro Moreschi is the only castrado to be recorded (presumably audio only, he died in 1922). Either you heard audio with him, or you saw someone that wasn’t technically a castrato.
Wiki does list a handful of recent/living male singers that are classified as castratos due to hormonal or other issues.
It might be worth checking on those few first, there’s not very many.

possibly one of these?
Yes this was a quartet of of mannish people with extraordinarily high voices ranging from about 7ish to 30-ish.

This is is darned close. I remember they were poised in profile in some dressed in red. I thought the background was white with everyone wearing red, but this is so close that I’m prepared to believe my mind is playing tricks on me.
