McCartney said that he "boycotted" Apple's offices after Klein's arrival in 1969. His continued isolation in 1970 led to Lennon, Harrison and Starr making business decisions without McCartney's input. One decision concerned the release of the "Let It Be" documentary, a necessity in order to fulfil the Beatles' contractual obligations to film company United Artists. McCartney privately agreed to a mid-April release date for "McCartney" with Apple Records executive Neil Aspinall, one of the few people associated with the Beatles who was aware of the project. Its late addition to Apple's schedule clashed with the imminent release of the "Let It Be" album, and of Starr's solo debut, "Sentimental Journey", which was due out on 27 March. On 25 March, after discovering that Klein arranged to have the release of "McCartney" postponed, McCartney received an assurance from Harrison, as a director of Apple Records, that his solo album would be issued on 17 April, as planned.
