market-place", was a reference to reggae singer Desmond Dekker, who had recently toured the UK. The tag line "Ob-la-di, ob-la-da, life goes on, brah" was an expression used by Nigerian conga player Jimmy Scott-Emuakpor, an acquaintance of McCartney. According to Scott's widow, as part of his stage act with his band Ob-La-Di Ob-La-Da, Scott would call out "Ob la di", to which the audience would respond "Ob la da", and he would then conclude: "Life goes on." After the release of "Ob-La-Di, Ob-La-Da" in November 1968, Scott tried to claim a writer's credit for the use of his catchphrase. McCartney said that the phrase was "just an expression", whereas Scott argued that it was not a common expression and was used exclusively by the Scott-Emuakpor family. McCartney was angry that the British press sided with Scott over the issue. According to researchers Doug Sulpy and Ray Schweighardt, in their study of the tapes from the Beatles' filmed rehearsals at Twickenham Film Studios in January 1969, McCartney complained bitterly to his bandmates about Scott's claim that he "stole" the phrase. Later in 1969, while in Brixton Prison awaiting trial for failing to pay maintenance to his ex-wife, Scott sent a request to the Beatles asking them to pay his legal bills. McCartney agreed to pay the amount on the condition that Scott abandon his attempt to receive a co-writer's credit.

He also double-tracked his vocal, which was not perfectly synchronised, creating an echoing effect. The formal recording of "Ob-La-Di, Ob-La-Da" took place in July and involved several days of work. The first completed version of the track, recorded between 3 and 5 July, featured Scott playing congas and a trio of saxophonists. At McCartney's insistence, the band remade the song in an effort to capture the performance for which he was aiming. In doing so, according to Beatles historian Mark Lewisohn, "the Beatles were creating another first: the first time they had especially recruited session musicians and then rejected the recording." Work began on the new version on 8 July. In the recollection of Geoff Emerick, the band's recording engineer, Lennon "openly and vocally detested" the
