Your Bird Can Sing", "She Said She Said", "I'm Only Sleeping" and "Tomorrow Never Knows". Richie Unterberger, in his review of the song for AllMusic, complimented the song's guitar pattern, being a possible influence from bands such as the Who. Unterberger also praises the vocal performances, particularly McCartney's high harmonies during the verses. Writing in his book Revolution in the Head, Ian MacDonald says that although the song is only a "minor" Beatles track, it is among the band's "most incisive pieces". He highlights the combination of Lennon's "caustic vocal", McCartney's "huckstering harmony in fourths" and Harrison's "double-tracked guitar, with its unique blend of sitar and country-and-western". Reviewing the album for Mojo in 2002, Charles Shaar Murray grouped "Doctor Robert" with "And Your Bird Can Sing", "She Said She Said" and "I Want to Tell You" as guitar-based tracks that "glisten" with "glorious cascades of jangle". He identified this jangle quality as the Beatles' response to "what the Byrds had done with the Fabs' own proto-folk-rock sound on A Hard Day's Night". When Mojo released Revolver Reloaded in 2006, part of the magazine's series of CDs of Beatles albums covered track-by-track by modern artists, "Doctor Robert" was covered by Luke Temple.
