Paul Is Dead:
INVOCATION OF MY DOUBLE
Things to note and observe:
When The Beatles enter the tent to watch the film, only Paul, John and Ringo are present. George appears on the screen.
Within the film itself, all 4 Beatles are present, which is witnessed in the Cello Fireworks sequence.
But when watching the film within the film, The Magical Mystical Boy, only George, John and Ringo are present. There is a shadow of a figure that is seen on the screen itself, but Paul is nowhere to be found. The film that plays beneath the figure of the Magical Mystical Boy is a sequence of shots involving what appears to be a naked person exiting a car, and another person gets out once the door is opened.
Can finally see what George, John & Ringo are watching in the Magical Mystical Boy film. Basically what plays underneath him, or on him, is a film of the audience in the tent watching the film. So a film, within a film, within a film. They then exit the tent, with the conductor allowing them out. It's a different shot sequence from the actual footage of them applauding the film and leaving the tent, because the old man with no teeth (who Lennon is seen laughing with at the beginning of the segment) leaves in a different fashion in the Mystical film, than he does in the The End version.
The end audio sequence is from the Death Cab for Cutie scene, where George & John are shown clapping for the Bonzo Dog Doo Dah Band and the Stripper. When played forwards, this audio has the audience, George & John clapping, with John making non-descript yelling noises. When this audio is reversed, John's yelling becomes one utterance of Paul's Dead. Some hear Paul Get In, which after the Death Cab for Cutie's subject matter, is still relevant.
