That's another good song. The worst is "Your Mother Should Know." All You Need Is Love is another bad one, probably my least favorite of their big hits.
Is the movie even out on dvd? The Rutles tried to parody it , but it's kind of beyond satire. Filmmakers in the 60's had yet to realize that drugs and editing do not mix.
"Flying" is an odd little number. It sounds like they're attempting to do improv but it never really goes anywhere. Though supposedly it's the only song in their catalog with writing credit to all four Beatles.
A friend of mine that used to work at a video duplication place had VHS bootlegs of a bunch of weird movies, including Magical Mystery Tour. It's pretty fucked up.
