On May 11, 1967, The Beatles recorded “Baby, You’re a Rich Man” in 12 takes at Olympic Sound Studios in London. It was the group’s first song that was not recorded and mixed at Abbey Road. The song was added as the B-Side to “All You Need Is Love” and released in July that summer. The single became a #1 hit worldwide and “Baby, You’re a Rich Man” even charted to #34 on the US Billboard Hot 100.
“Baby, You’re a Rich Man” is a combination of two separate Lennon and McCartney song snippets: Lennon’s working-title song “One of the Beautiful People” and a chorus McCartney was working on, “Baby, you’re a rich man.” The duo had done a mash-up of their melodies previously on “A Day in the Life” (from the Sgt. Pepper LP).
It’s believed Mick Jagger was present in the studio during the Beatles recording and may have sang on the final mix’s chorus.
The song was intended for the Yellow Submarine soundtrack, but Capitol Records added it to its version of the Magical Mystery Tour album for release in the US.
In the UK, Magical Mystery Tour was a four-sided EP (extended play) recording with “Magical Mystery Tour,” “Your Mother Should Know,” “I Am the Walrus,” “The Fool on the Hill,” “Flying” and “Blue Jay Way.”
Capitol in the US packaged the additional Beatles singles that had not appeared on any albums, including the “Strawberry Fields Forever/Penny Lane” pairing (which were actually recorded at the start of the Sgt. Pepper sessions).
“Baby, You’re a Rich Man” gained a new audience with its inclusion in the closing credits of David Fincher’s 2010 film, The Social Network.
