In September 1969, John Lennon privately informed his bandmates that he was leaving the group, but there was no public acknowledgement of the break - up until 10 April 1970, when Paul McCartney announced he was leaving the band . </P> <P> There were numerous causes for the band's break - up; it was not a single event but rather a long transition . Some of the factors contributing to the separation include the cessation of touring in 1966 and the death of their manager Brian Epstein in 1967 . Conflicts also arose from differences in artistic vision . Both George Harrison and Ringo Starr temporarily left the group at various points during 1968--69 and all four band members had begun working on solo projects by 1970 as they all realised the likelihood the band would not regroup . Ultimately, animosity made it impossible for the group to continue working together in the years following . </P>
