YouTube videos on Carnival of Light

I've been looking through YouTube to see if there is an actual recording of the song that somehow got on there. Most of them are claimed fake from the comments though. Here are some examples I have found.

Claims to be the original yet doesn't fit the description all to well. Comments claim it's fake, too. https://youtu.be/A5p6z8QAVYU

(Starts and ends at 0:00-0:24) Fake, you can hear some clips of the orchestrations of A Day In The Life. One point of interest though: a comment claims that some people say that some clips of the song have appeared on the album "LOVE" in the songs "Being for the Benefit of Mr. Kite," "I Want You (She's so Heavy)," and "Helter Skelter." I have yet to research this and see if it's true, but I will post updates when I get around to listening them (so, never.) https://www.youtube.com/watch?v=WmJFKCNTEnU

This one is just a recreation: https://youtu.be/OPJIbKAcAQ4

This one claims to be the official recording, but a comment says it's just the song "Sun of Suzy Creamcheese," backwards from the band Mothers of Invention. Have yet to see if this is true, though. https://www.youtube.com/watch?v=vXc9W_r5c30

The publisher claims that his father was able to get an excerpt of the song. Obviously fake, as, according to the comments, the "NOW" scream is from one of their Christmas records. It's also too "rock-y" to be avant-garde. Good song, though. https://www.youtube.com/watch?v=_dUO2Wr_kRo

All of these don't seem to fit the description all to well (or at least I think so, I only really skimmed through them.) If anyone has a source that they think is Carnival of Light, please post it.
