put on hold, the group continued to record together sporadically during the spring and early summer of 1969. Otherwise, the band members became increasingly involved in activities outside the band; among these, Lennon launched an international peace campaign with Ono, spearheaded by their single "Give Peace a Chance"; Harrison continued to focus on producing Apple Records signings, including Jackie Lomax, Billy Preston and devotees from the London Radha Krishna Temple; and Starr began to establish himself as a film actor. Their occasional sessions together over the first half of the year ultimately paved the way for the Beatles' last studio recording project, Abbey Road. The 18 August session for "The End" marked the final occasion that all four members recorded collectively. The last time the foursome were together in the same studio was for the completion and mixing of "I Want You (She's So Heavy)" two days later. On 8 September, while Starr was hospitalised, Lennon, McCartney and Harrison met to discuss recording a follow-up to Abbey Road. In the meeting Lennon and Harrison expressed frustration with having to compete with McCartney to get their songs recorded. Lennon proposed a different approach to songwriting by ending the Lennon–McCartney pretence and having four compositions apiece from Lennon, McCartney and Harrison, with two from Starr and a lead single around Christmas. Harrison referred to the possibility of a new Beatles album in an interview he gave in November, and he called this songwriting arrangement "an equal rights thing". McCartney later dismissed the new division of songwriting, saying it "wasn't the right balance" and was "too democratic for its own good". Speaking to Melody Maker in September, Lennon said: "The trouble is we've got too much material. Now that George is writing a lot, we could put out a double album every month ..." During the 8 September meeting, McCartney expressed that, before Abbey Road, he "thought that George's songs weren't that good", to which Lennon reacted by saying none of the other Beatles liked McCartney's "Ob-La-Di, Ob-La-Da" and "Maxwell's Silver Hammer" and that those types of songs should be given to other artists to record. Soon after the sessions for Abbey Road, Lennon's heroin use inspired him to record "Cold Turkey" with his and Ono's conceptual group, the Plastic Ono Band, after the Beatles had rejected the song for release as a single. The formation of the Plastic Ono Band was conceived
