on "Baby, You're a Rich Man": "The energy level was so intense … that you were riding wave upon wave of amazing creativity. It was like watching a well-oiled machine. Just incredible." According to another Olympic staff engineer, Grant and Kramer were highly complimentary of Lennon as a vocalist and "couldn't believe anyone could sing that well". Aside from the clavioline part, overdubs on the track included maracas and tambourine, and vibraphone played by Kramer. Only a single note of the vibraphone is clearly audible throughout the track, at the 0:53 mark. McCartney recalled the six-hour session as an energetic one and "rather exciting", adding: "Keith Grant mixed it, instantly, right there. He stood up at the console as he mixed it, so it was a very exciting mix, we were really quite buzzed." During the session, Lennon changed a line in the chorus to "Baby, you're a rich fag Jew".

Partly as a result of these disruptions, the Beatles required twelve takes before they achieved a satisfactory rhythm track. The group enjoyed working at Olympic Sound, which was an independent facility, free of record company control. They returned to Barnes on 14 June to record the basic track for "All You Need Is Love".

While parts of the song were used in the film, its initial release was as the B-side of "All You Need Is Love", which the Beatles performed on the Our World satellite broadcast on 25 June 1967 and then rush-released as a single. The release took place on 7 July in the United Kingdom and on 17 July in the United States. "All You Need Is Love" topped singles charts in many countries around the world. In the United States, the B-side also charted in its own right, peaking at number 34 on the Billboard Hot 100 and number 60 on the Cash Box Top 100. In Australia, it was listed with "All You Need Is Love", as a double A-side, when the single topped the Go-Set national chart. The single followed soon after Sgt. Pepper,
