the majority of the Beatles' catalogue. The first two UK studio albums included 12 cover tunes and 15 Lennon–McCartney songs, with one track ("Don't Bother Me") credited to George Harrison. Their third UK album, A Hard Day's Night (1964), is the only original Beatles album made up entirely of Lennon–McCartney compositions. The next album released, Beatles for Sale (1964), included six covers and eight Lennon–McCartney originals. The subsequent release, Help! (1965), had two covers and two Harrison compositions along with ten Lennon–McCartney tracks; it was the last Beatles album to feature a non-original composition until Let It Be, which included an arrangement of the traditional Liverpool folk song "Maggie Mae". Among the songs in this post-Help! output, Harrison contributed between one and four songs per album, and Starr wrote two songs in total and received a joint credit with Lennon and McCartney for a third ("What Goes On"). In addition, "Flying" and "Dig It" were credited to all four Beatles. The rest of the catalogue came from Lennon and McCartney. Lennon and McCartney gave songs to Starr to sing, and to Harrison before he started writing his own material. As for the songs they kept for themselves, each partner mostly sang his own composition, often with the other providing harmonies, or they shared lead vocal. If each contributed a fragment to make a whole song, he might sing his portion, as in the case of "I've Got a Feeling" and "A Day in the Life". "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). McCartney sings in unison with Lennon on the verses, but Lennon's vocal is more prominent. McCartney sings the high harmony on the chorus. 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. Under US copyright law, for works published before 1978 the author can reclaim copyrights assigned to a publisher after 56 years. McCartney and Sony agreed to a confidential settlement in June 2017. Non-Beatles songs Several songs credited to Lennon–McCartney were originally released by bands other than the Beatles, especially those managed by Brian Epstein. Recording a Lennon–McCartney song helped launch new performing-artists' careers. Many of the recordings below were included on the
