The Beatles were originally supposed to voice the vultures in The Jungle Book.

The Beatles’ manager had worked out an agreement with Walt Disney for the group to perform in the film, but this dream was shot down when he approached the group with the idea. John Lennon reportedly shouted, “There’s no way the Beatles are going to sing for Mickey ****-ing Mouse!” Nevertheless, the four vultures are still modeled after the Fab Four, and the final product retains the Liverpool accent and mop-top haircuts as an homage to the group (the quiet vulture with the shaggy hair is a dead ringer for George!).

Much as I would’ve liked to have seen the Beatles in a Disney movie, I think I prefer the barbershop music anyway:
