In 1974 The Beatles were officially and legally disbanded.
The story has been well documented, Hell there's a great docuseries about it on Apple+, but the recording fiasco that would eventually lead to the album "Let It Be" would become the last gasp of the iconic band.
The aftermath of all the announcements and business lobbying would lead to Paul McCartney filing suit for the dissolution of The Beatles' contractual partnership on December 31, 1970, but, this would begin the FOUR YEAR LONG battle between varying management teams and companies. It's notable here that the beatles weren't only connected musically as a band but corporately as a business association with their label and production companies, as well as Beatles management. The legal disputes would continue even after their break-up, so the dissolution was not formalised until this day in 1974. John Lennon would sign the paperwork terminating the partnership at Walt Disney World Resort in Florida of all places. So, Mickey Mouse was literally on hand to see then end of The Beatles.
It's a small, small, world.
