Yellow Submarine/WMG

The Lord Mayor is Old Fred's dad.
Why else would the lord Mayor call Fred 'Young Fred' with a heartwarming hug when he and the Beatles get back to Pepperland?
 * Well, he could also be a nephew or cousin, and still a close relative.

The "Hey Bulldog" footage didn't really exist before the film was remastered.
Has anyone seen it in the initial British release?

This footage makes a drastic difference to the film's tone. In the vs. without it which was in circulation in America between release and 1991, the "All You Need Is Love" sequence and its immediate aftermath is an overpowering triumph for the side of good -- a practical steamroller. In the restored vs., even when good has mostly triumphed, it is a longer and closer battle.

That there are "Magical Mystery Tour" references in a film which had most of the vocal track recorded before "Sgt. Pepper's" doesn't help.

There was a switch between the Beatles and Sgt. Pepper's Lonely Hearts Club Band at the end of the newer film.
We get a better look at the second band in the newer film, and they look more like the Fab Four we see in live action at the end than the cartoon Beatles in the beginning do.
