If you want to get to the heart of this, I suggest you just watch Video No.5. Why? Because it hardly mentions the "Paul is Dead" malarkey.

What it does say is about Mal Evans, the book he was writing when he was mysteriously shot in LA, and the fact that 4 years after Neil Aspinall's death is 2012. The implication (if I read it right) is that Aspinall got hold of Evans's manuscript and sat on it until it could be safely released.

Watching the last few minutes, you see typescripts with various highlighting and lines drawn to link names. The phrase "OTO" pops up several times. This is the Ordo Templi Orientis, an occult fraternity founded by none other than Aleister Crowley (whose picture appears regularly during the documentary): [link to en.wikipedia.org]

There are also several suggestive photos of Paul wearing "magical" outfits and lots of codes in the Beatles' album covers and imagery that reference the Western magickal tradition.

Also in previous videos there's a lot of links being made between Charles Manson, the Sharon Tate murders and the Beatles lyrics. Are they hinting at some deeper connection there?

I reckon that when the book/film emerges in 2012, it will address the "Paul is Dead" stuff but the really explosive revelations will be about the Beatles, the occult lodges of Los Angeles and the real fate of Mal Evans's typescript. Possibly it was all put together by Aspinall and kept down until he was safely dead.

Two further questions:
1. what did Heather Mills discover about Paul that so frightened her and was "worse than infidelity"?
2. How come Mal Evans said he was going to get joint credits on some of the Beatles songs, hours before he was shot?

All kinds of intrigue here!
