- Bad Export for You: As usual with American versions of the Fab Four's albums before Sgt. Pepper's Lonely Hearts Club Band. The US release deleted three songs ("I'm Only Sleeping", "And Your Bird Can Sing" and "Dr. Robert") which Capitol had already released on their Yesterday and Today album. Since all three were John Lennon songs, this made the American album lopsided in favor of Paul McCartney's contributions. America didn't get a complete version of Revolver until the 1987 CD release, when all the US-only Beatles albums were replaced by their British equivalents.
- Throw It In: The backwards guitar part on "I'm Only Sleeping" was the result of an EMI engineer accidentally putting a tape on backwards in the studio.
- Unintentional Period Piece: In the song "Taxman" British politicians Harold Wilson and Edward Heath are referenced, making it one of the few Beatles songs that directly reference 1960s society. When George later performed the song in concert in 1991 (in what would be released on his Live in Japan album), he updated the lyrics slightly, adding another verse changing the political references to ones more relevant of the era (John Major, Boris Yeltsin, George H.W. Bush).
- What Could Have Been: According to a 1966 letter from George Harrison to an Atlanta DJ, the Beatles nearly recorded the album at Stax Records in Memphis (home of Otis Redding, Isaac Hayes, Sam & Dave, Booker T. & the MG's, etc.), but the deal fell through over money issues.
- "Father MacKenzie" in "Eleanor Rigby" almost was written as "Father McCartney" as John and Paul liked the sound of the name, before Paul decided he didn't want to offend his father.
