[1] Between 5 October 1962 and 8 May 1970, the partnership published approximately 180 jointly credited songs, of which the vast majority were recorded by the Beatles, forming the bulk of their catalogue.
Unlike many songwriting partnerships that comprise a separate lyricist and composer, such as George and Ira Gershwin, Richard Rodgers and Oscar Hammerstein II, Kander & Ebb or Elton John and Bernie Taupin, both Lennon and McCartney wrote lyrics and music.
By an agreement made before the Beatles became famous, Lennon and McCartney were credited equally with songs that either one of them wrote while their partnership lasted.
The 15-year-old McCartney, brought along by a mutual friend, Ivan Vaughan, impressed Lennon with his ability on the guitar and his version of Eddie Cochran's "Twenty Flight Rock".
[5][6] The duo's first musical idols were the Everly Brothers, Little Richard, Chuck Berry, Elvis Presley, Buddy Holly, and Smokey Robinson and the Miracles, and they learned many of their songs and imitated their sound.
[7] Their first compositions were written at McCartney's home (20 Forthlin Road), at Lennon's aunt Mimi's house (251 Menlove Avenue), or at the Liverpool Institute.
[8] They often invited friends—including George Harrison, Nigel Walley, Barbara Baker, and Lennon's art school colleagues—to listen to performances of their new songs.
[10] In Lennon's 1980 Playboy interview, he said of the partnership: [Paul] provided a lightness, an optimism, while I would always go for the sadness, the discords, the bluesy notes.
However, it does not tell the whole story, as some of McCartney's most characteristic songs are tragic, or express themes of isolation, such as "Yesterday", "She's Leaving Home", "Eleanor Rigby" or "For No One".
"A Day in the Life" is a well-known example of a later Beatles song that includes substantial contributions by both Lennon and McCartney, where a separate song fragment by McCartney ("Woke up, fell out of bed, dragged a comb across my head ...") was used to flesh out the middle of Lennon's composition ("I read the news today, oh boy ...").
"In Spite of All the Danger", a 1958 song that the band (then the Quarrymen) paid to record to disc, is attributed to McCartney and George Harrison.
"Woman" by Peter and Gordon in 1966 (McCartney using Bernard Webb as a pseudonym), "Cat Call" by Chris Barber in 1967, and "Penina" by Carlos Mendes in 1969).
After the partnership had ended, Lennon and McCartney each gave various accounts of their individual contribution to each jointly credited song, and sometimes claimed full authorship.
[48] Subsequent Paul McCartney live albums Good Evening New York City (2009) and Amoeba Gig (2019) featured original credit to Lennon-McCartney songs.
The new Paul McCartney and Wings live-in-the-studio album One Hand Clapping (2024) featured reverted credits to the Beatles songs.
Ellie Greenwich, a Brill Building songwriter, said, "When the Beatles and the entire British Invasion came in, we were all ready to say, 'Look, it's been nice, there's no more room for us… It's now the self-contained group- makes, certain type of material.
[54] The Lennon–McCartney brand would prove to be a model for several other songwriting teams in the rock genre, including, according to Lennon, the Rolling Stones' Jagger–Richards partnership.
The first two UK studio albums included 12 cover tunes and 15 Lennon–McCartney songs,[66][67] with one track ("Don't Bother Me") credited to George Harrison.
"Every Little Thing" is a rare example of a Lennon–McCartney song in which one member of the partnership was primary composer (McCartney) but the other sang lead vocal (Lennon).
In January 2017, McCartney filed a suit in United States district court against Sony/ATV Music Publishing seeking to reclaim ownership of his share of the Lennon–McCartney song catalogue beginning in 2018.
[82] The list of unreleased songs includes some of the earliest Lennon–McCartney joint works dating back to the Quarrymen, the group that evolved into the Beatles.
