full_context: Document 1: Julia Lennon: Julia Lennon (née Stanley; 12 March 1914 – 15 July 1958) was the mother of English musician John Lennon, who was born during her marriage to Alfred Lennon. After complaints to Liverpool's Social Services by her eldest sister, Mimi Smith (née Stanley), she handed over the care of her son to her sister. She later had one daughter after an affair with a Welsh soldier, but the baby was given up for adoption after pressure from her family. She then had two daughters, Julia and Jackie, with John 'Bobby' Dykins. She never divorced her husband, preferring to live as the common-law wife of Dykins for the rest of her life.

Document 3: She's Always a Woman: The song was released in 1977, following several other hits from The Stranger including ``Just the Way You Are '',`` Movin 'Out (Anthony's Song)'' and ``Only the Good Die Young ''. Musically, Joel has said that he was influenced by Gordon Lightfoot and his mellow acoustic guitar ballads. It is a love song that Joel wrote for his then wife, Elizabeth Weber. Elizabeth had taken over management of Joel's career, and was able to put his financial affairs in order after Joel had signed some bad deals and contracts. She was a tough and savvy negotiator who could`` wound with her eyes'' or ``steal like a thief '', but would`` never give in''. Because of her tough - as - nails negotiating style, many business adversaries thought she was ``unfeminine, ''but to Joel, she was always a woman. The two eventually divorced in 1982.

Document 5: Tight A$: "Tight A$" is a song written by John Lennon released on his 1973 album "Mind Games". The song is also included in the 2010 compilation album, "Gimme Some Truth". A tongue-in-cheek rocker, Lennon managed to get the phrase "tight ass" past the censors.
Document 6: Jealous Guy: ``Jealous Guy ''is a song by English rock musician John Lennon from his 1971 album Imagine. Lennon began writing the song in 1968, when, as`` Child of Nature'', it was among the many songs demoed by the Beatles before they recorded their self - titled double album (also known as the ``White Album ''). The lyrics were originally inspired by a lecture given by Maharishi Mahesh Yogi in early 1968, when the Beatles attended his spiritual retreat in Rishikesh, India. In its rewritten form, the song serves as a confessional in which Lennon addresses the feelings of inadequacy that resulted in his failings as a lover and husband.
Document 7: Julia Baird: Julia Baird (née Dykins; born 5 March 1947) is a British retired teacher and author. She is the younger half-sister of English musician John Lennon, and is the eldest daughter of his mother Julia Lennon (12 March 1914 – 15 July 1958) and John 'Bobby' Albert Dykins (1918 – December 1965).

Document 8: Early 1970: "Early 1970" is a song by English musician Ringo Starr, released in April 1971 as the B-side to his hit single "It Don't Come Easy". It was inspired by the break-up of the Beatles and documents Starr's relationship with his former bandmates, John Lennon, Paul McCartney and George Harrison. The lyrics to the verses comment in turn on each of the ex-Beatles' personal lives and the likelihood of each of them making music with Starr again; in the final verse, Starr acknowledges his musical limitations before expressing the hope that all the former Beatles will play together in the future. Commentators have variously described "Early 1970" as "a rough draft of a peace treaty" and "a disarming open letter" from Starr to Lennon, McCartney and Harrison.
Document 9: Jack London: Jack London's mother, Flora Wellman, was the fifth and youngest child of Pennsylvania Canal builder Marshall Wellman and his first wife, Eleanor Garrett Jones.  Marshall Wellman was descended from Thomas Wellman, an early Puritan settler in the Massachusetts Bay Colony. Flora left Ohio and moved to the Pacific coast when her father remarried after her mother died. In San Francisco, Flora worked as a music teacher and spiritualist, claiming to channel the spirit of a Sauk chief, Black Hawk.Biographer Clarice Stasz and others believe London's father was astrologer William Chaney. Flora Wellman was living with Chaney in San Francisco when she became pregnant. Whether Wellman and Chaney were legally married is unknown. Most San Francisco civil records were destroyed by the extensive fires that followed the 1906 earthquake; nobody knows what name appeared on her son's birth certificate. Stasz notes that in his memoirs, Chaney refers to London's mother Flora Wellman as having been his "wife"; he also cites an advertisement in which Flora called herself "Florence Wellman Chaney".According to Flora Wellman's account, as recorded in the San Francisco Chronicle of June 4, 1875, Chaney demanded that she have an abortion. When she refused, he disclaimed responsibility for the child. In desperation, she shot herself. She was not seriously wounded, but she was temporarily deranged. After giving birth, Flora turned the baby over for care to Virginia Prentiss, an African-American woman and former slave. She was a major maternal figure throughout London's life. Late in 1876, Flora Wellman married John London, a partially disabled Civil War veteran, and brought her baby John, later known as Jack, to live with the newly married couple. The family moved around the San Francisco Bay Area before settling in Oakland, where London completed public grade school.
