John Lennon and Paul McCartney were an unrivalled song-writing partnership but their relationship soured in the late 1960s. Tensions within The Beatles simmered in the second half of the decade, affecting recording sessions for 'The White Album', 'Let it Be' and 'Abbey Road'.
Creative differences and the presence of Yoko Ono in the studio caused arguments, pushing John and Paul away from each other. The band's final recording sessions - for 'The End' which featured on 'Abbey Road' - took place in August 1969 and, a month later, John informed his fellow members that he was leaving the band, asking for a 'divorce' from The Beatles.
This led a saddened Paul to retreat to his home and record what would become his first solo album 'McCartney'. In April 1970, Paul issued a press release alongside that album, announcing he would no longer be working with The Beatles.
The final Beatles album 'Let it Be' then hit shelves in May 1970, nearly a month after the official break up. 'Let it Be' was made up of recordings dating between February 1968 and April 1970 and its release caused further disagreements between Paul, John, Ringo Starr and George Harrison.
An ongoing row about Allan Klein becoming the band's new manager had simmered throughout 1969 and caused the four stress about what would happen to their money and the future of their music. That row developed as the release of 'McCartney' was set to clash with the planned May release of 'Let It Be'.
Paul has said he told his bandmates in advance that he would release 'McCartney' alongside his press release announcing his departure from The Beatles in April 1970. But with record label Apple wanting to avoid a clash and Paul not wanting to speak to Apple due to his disapproval of Allan Klein, Ringo went to his home with a letter from himself, John and George asking him to move his release date.
