It was 51 years ago Saturday (April 10th, 1970) that Paul McCartney's departure from the Beatles was made public, in effect announcing to the world what many fans had suspected over the past six months — the Beatles had broken up. McCartney's statements regarding the end of his songwriting partnership with John Lennon, along with his wish to record apart from Lennon, George Harrison and Ringo Starr, came as part of a question-and-answer sheet included with press copies of his debut solo album, which was simply titled McCartney.
The news had first leaked out three days prior to that. McCartney's brother in-law and attorney John Eastman let McCartney's break with the band slip while announcing plans for McCartney's plans for an animated film of the British animated character Rupert the Bear and the upcoming release of McCartney's debut album.
In the Q&A for the press, which was actually written entirely by McCartney, he asked himself several pointed questions about the future of the group. McCartney explained his reasons for going solo, citing “business and musical differences, but most of all because I have a better time with my family.” McCartney went on to issue what most fans read as the ultimate death knell to the Beatles: “I do not foresee a time when the Lennon & McCartney partnership will be active again in songwriting.”
