Story 
“Eleanor Rigby” is a song by the English rock band the Beatles from their 1966 album Revolver. It was also issued on a double A-side single, paired with “Yellow Submarine”. Credited to the Lennon–McCartney songwriting partnership, the song is one of only a few in which John Lennon and Paul McCartney later disputed primary authorship. [Wikipedia]
McCartney wrote the song — name and theme — as a meditation on loneliness, the lyric collated over months. The name ‘Eleanor’ came from the actress Eleanor Bron (then in Help!); ‘Rigby’ was a Bristol shop name McCartney had noticed. A 1980s headstone discovery at St Peter’s Church in Woolton — where Lennon and McCartney had first met — bore the name ‘Eleanor Rigby’ and is widely assumed to have been a buried memory. Paul McCartney’s elegiac composition ‘Eleanor Rigby’ marked a watershed moment in Beatles artistry: a song with no guitar, bass, or drum accompaniment, supported solely by a string arrangement. The character study of an aging woman’s loneliness reflected McCartney’s growing confidence as composer-arranger, moving beyond the rhythmic foundation that had defined earlier work. George Martin’s string octet, with cellos and violins arranged in sparse, mournful counterpoint, transformed pop songwriting tradition (Lewisohn 1988, p.82). Kozinn situates ‘Eleanor Rigby’ within McCartney’s thematic arc on Revolver, working at a higher compositional level to produce ‘a tender, descriptive ballad, sung in pristine’ vocal clarity—distinct from other McCartney offerings on the album in its stark imagery of social alienation. (Kozinn 1995, p.146)
Cut 28 April 1966 with no Beatle playing any instrument: McCartney sings to a string octet (four violins, two violas, two cellos) arranged by George Martin in a deliberate Bernard Herrmann tribute. Harrison and Lennon contribute the vocal harmony in the chorus. The string arrangements were recorded separately on 28 April 1966, with McCartney’s lead vocal and backing harmony lines overdubbed onto pre-recorded orchestral tracks. The integration of vocal and string parts required precise microphone technique and level control, as no rhythm instruments existed to anchor the mix. George Martin’s orchestration captured the composition’s funeral gravity without resorting to sentimentality, while Geoff Emerick’s engineering ensured each string voice remained distinct and audible (Lewisohn 1988, p.82). Emerick recalls the challenging recording process of ‘Eleanor Rigby,’ where George Martin arranged string accompaniment after Paul performed the song on acoustic guitar. The stringed octet was achieved in minimal takes, though Martin flew in the string section again during the fadeout mix. (Emerick 2006, p.337) MacDonald identifies this as a pivotal turning point where McCartney’s songwriting matured beyond typical pop structures, with the song becoming a UK single that notably failed to reach No. 1 in America, departing from Beatles’ chart dominance.
