I heard about this conspearicy a while ago, and decided to do a bit of research on it. this is what i came up with as a final result. Enjoy....
"Paul is a dead man, miss him, miss him, miss him."
Just one of the many reversed lyrics by the beatles. I have noticed that if you play some of their songs in revease, like 'I'm so tired' (The lyrics as shown above) read messages about Paul's (a band member's) death. Here's some examples:
Stawberry Fields Forever- "I buried Paul"
I Am The Walrus- "Paul is dead"
Okay, so maybe that's not enough proof for you? Well rumors suddenly spread all over that Paul McCartney was infact, dead. John Lennon had apparently sent Paul off driving while he was drunk, intending to get him into a car crash. Here are some messages that the beatles have been trying to tell us:
In the song 'I am the walrus', there is a bunch of symbolic elements. for example in the song "Sitting on a cornflake - waiting for the van to come." The corn flake represensts the crashed car that Paul is sitting dead in. The van waiting for his ambulence that will never come" even the chorus 'I am the Walrus" John is posing as Paul and the walrus is actually the Noregion symbol of death. Some other lyrics proving Paul's death:
* john sings "goo goo goo joob", which are supposedly (where they get this from, i have no idea) humpty dumpty's last words before he fell off the wall and broke his *head*.
* "choking smoke" -- from the crash and fire?
* "Pretty little policemen in a row" -- the infamous meter maid???
* "Yellow matter custard, dripping from a dead dog's eye" -- not to get vulgar, but maybe paul's brain dripping from his cracked head??
One of the beatles less known songs is called "Revolution 9." Basically, the whole song is the beatles saying the phrase "Number nine" over and over again. And guess what? McCartney has 9 letters! In the background of the song, you can actually hear Paul screaming "Get me out! Get me out!". And the even creepier part, is that the lyric played in reverse says clearly: "Turn me on, dead man"
I have reason to believe that Paul, a former beatle is DEAD, as of 1966. John Lennon sent him driving into his death, and was taken away secretly. Paul was replaced by a look-alike since. Here's some more stuff for you to read about...

The cover shows the Beatles walking across Abbey Road. John is dressed in white, as the preacher at a funeral (preferably Paul's). Ringo is dressed as pallbearer, Paul, who is out of step, barefoot, and holding a cigarette in his right hand when he is proven to be a left hander, is the corpse. And George is dressed like the grave digger. A Volkswagon has a license plate that says "28 if", meaning, Paul would be 28 if he were alive still.
After 1966 the fake Paul played with his right hand ever since, when before when the real one was ALIVE, he played with his left hand.
How about that Yellow submarine movie? The movie has a couple of clues, one happens during the song "All You Need Is Love" when John sings "..yes, he's dead.." the word "know" on the screen changes into the word "now" at the same moment.
On the Sgt. Pepper cover:
the interior of the small car held by the doll is blood red; was it like this when paul's head was crushed or whatever happened to him?
paul is the only beatle facing directly forward, supposedly because the others were posing with a life-size cut-out of him for the cover photo.
the "younger" paul is consoling the "younger" ringo, who looks like he's looking down into a grave (all four of them are looking down like that)
the flowers in the shape of the bass are actually over what is supposed to be paul's grave, and the bass looks peculiarly like the one paul played most often; it's even supposedly left-handed.
paul is the only beatle to be holding a black instrument; an english horn, which is also the only one of the four of them holding an instrument not from a marching band.
one of the patches of yellow flowers looks like a flaming car going off a cliff; i think it's the patch that the little doll is looking at.
And finally, the oddest thing yet....
First take either the album LP cover or CD cover and look for the drum. Notice the letters lonely hearts. Place the edge of a butter knife or mirror across the center of the letters reading HEARTS and it will read "HE ^ DIE" pointing straight up to Paul.
