Oh my god "Magical Mystery Tour" sucks. Yet it's the most Beatley movie they made — the only one they wrote, directed & acted in. They acted in "A Hard Day's Night" and "Help!", but they didn't write or direct those. And they're not even *in* "Yellow Submarine". They have a voice cameo, but actors play the Beatles in the entire rest of the movie. But man, I will watch "Magical Mystery Tour" a hundred times over because it features the Bonzo Dog Doo-Dah Band. Because BONZOS.
The art of the laugh track is to make it raucous enough to let you know it's funny, but not identifiable enough to pick out any one person laughing. If you could identify people laughing, it would shatter the illusion that the on-screen laughter is actually yours.
