Having exhausted the extensions of their American visas, Lennon and Ono returned from the US on 15 September 1970. Soon afterwards, Ono
miscarried at close to eight months pregnant, and Lennon's equilibrium was tested when his father,
Alf Lennon, resumed contact, having recently remarried and become a father again. At Alf's request, they met up at
Tittenhurst Park for Lennon's 30th birthday, but Lennon launched into a primal therapy-inspired tirade against him and, according to the account Alf left with his solicitor, threatened to kill him. Recording for the album took place at
Abbey Road Studios in London, beginning on 26 September. Lennon played guitar or piano on the songs, with bassist
Klaus Voormann and drummer
Ringo Starr as the other core musicians. The album title refers to the
Plastic Ono Band, the conceptual band Lennon and Ono formed in 1969 of various supporting musicians they would use on their various solo albums. Lennon asked
Phil Spector, who had produced Lennon's hit "
Instant Karma!" earlier that year, to co-produce the new album. Since they were unable to contact Spector before recording began,
Allen Klein, Lennon's manager, took out an advertisement in
Billboard magazine that read: "Phil! John is ready this weekend." Spector and Apple artist
Billy Preston each played piano on a track. During the sessions, Lennon, Voormann and Starr jammed on a variety of songs in between recording the new tracks: "When a Boy Meets a Girl", "
That's All Right Mama", "
Glad All Over", "
Honey Don't", "
Don't Be Cruel", "
Hound Dog" and "
Matchbox". They also taped the basic track for Starr's "
Early 1970" in which the drummer describes his relationship with each of his former bandmates; in the verse dedicated to Lennon, Starr sings, "They screamed and they cried, now they're free". As longstanding friends of Lennon, Voormann and Starr were disturbed by his emotional behaviour in the studio. In his 2004 book
Postcards from the Boys, Starr recalls that Lennon would burst out crying or start screaming midway through recording a track. Voormann said that Lennon would change from being upbeat to highly emotional and would discuss his feelings with Ono as they listened to playbacks in the studio control room. In Voormann's view, the effects of Lennon's therapy were especially confronting to Starr, since "The old John was gone; it was a different John. It wasn't the one he was used to." According to music critic
Richie Unterberger, bootlegs from the sessions suggest that Lennon was far from the despondent artist reflected in the finished album. As the ensemble recorded "Remember" on 9 October, Lennon's 30th birthday,
George Harrison visited the studio and delivered a tape of "
It's Johnny's Birthday", after Ono had asked Lennon's friends for musical greetings to mark the occasion. The session tapes reveal Lennon and Starr's delight at Harrison's arrival. In author Robert Rodriguez's description, the meeting reflects the three former Beatles' closeness, at the expense of
Paul McCartney, as well as Lennon's playfulness while making
Plastic Ono Band. Lennon and Ono produced
Plastic Ono Band largely on their own, as Spector was absent for much of the recording sessions. Spector
mixed the album for three days towards the end of October. All work on the record was completed by 27 October, when Lennon and Ono flew to New York to publicise primal therapy and collaborate on the experimental films
Up Your Legs Forever and
