Some context: Nilsson was born in Bedford-Stuyvesant, Brooklyn in 1941. His paternal grandparents were Swedish circus performers and dancers, especially known for their "aerial ballet" (which is the title of one of Nilsson's albums). His maternal grandparents were the cornerstone of his young life. While his grandmother played piano, his grandfather Charlie supported the family in a tiny railroad apartment on Jefferson St in Brooklyn.
Nilsson is the subject of a 2006 documentary, Who Is Harry Nilsson (And Why Is Everybody Talkin' About Him)? produced by David Leaf and John Schienfeld. The film was screened in 2006 at the Seattle International Film Festival and the Santa Barbara International Film Festival. In August 2006, the film received its Los Angeles premiere when it was screened at the 7th Annual Mods & Rockers Film Festival followed by a panel discussion about Nilsson featuring the filmmakers and two friends of Nilsson, producer Richard Perry and attorney/executive producer Lee Blackman.  The filmmakers re-edited the film with rare found footage of Nilsson, further interviews, and family photographs, and finally released it on September 17, 2010 at selected theaters in the United States. A DVD, including additional footage not in the theatrical release, was released on October 26, 2010.  Nilsson's final album, tentatively titled Papa's Got a Brown New Robe (produced by Mark Hudson) was not released, though several demos from the album were available on promotional CDs and online.  The musical Everyday Rapture features three songs by Nilsson and, similarly, the film A Good Year features "Gotta get up", "Jump into the fire" and "How can I be sure of you".  On July 29, 2013, Sony Music released a definitive box-set of his RCA era albums called The RCA Albums Collection. Each of the albums in the 17-CD set had additional bonus tracks, along with 3 of the 17 discs that contained rarities and outtakes spanning his entire career. Additionally, several weeks later on August 13, Flash Harry was finally issued on CD also featuring additional material. Completing the two CD releases, the first book written about Nilsson was published covering his life story.

Some context: Zenzile Miriam Makeba (4 March 1932 - 9 November 2008), nicknamed Mama Africa, was a South African singer, actress, United Nations goodwill ambassador, and civil-rights activist. Associated with musical genres including Afropop, jazz, and world music, she was an advocate against apartheid and white-minority government in South Africa. Born in Johannesburg to Swazi and Xhosa parents, Makeba was forced to find employment as a child after the death of her father. She had a brief and allegedly abusive first marriage at the age of 17, gave birth to her only child in 1950, and survived breast cancer.
Following growing pressure from the anti-apartheid movement both domestically and internationally, in 1990 State President Frederik Willem de Klerk reversed the ban on the African National Congress and other anti-apartheid organisations, and announced that Mandela would shortly be released from prison. Mandela was released in February 1990. He persuaded Makeba to return to South Africa, which she did, using her French passport, on 10 June 1990.  Makeba, Gillespie, Simone, and Masekela recorded and released her studio album, Eyes on Tomorrow, in 1991. It combined jazz, R&B, pop, and traditional African music, and was a hit across Africa. Makeba and Gillespie then toured the world together to promote it. In November she made a guest appearance on a US sitcom, The Cosby Show. In 1992, she starred in the film Sarafina!, which centred on students involved in the 1976 Soweto uprising. Makeba portrayed the title character's mother, Angelina, a role which The New York Times described as having been performed with "immense dignity".  On 16 October 1999, Makeba was named a Goodwill Ambassador of the Food and Agriculture Organization of the United Nations. In January 2000, her album, Homeland, produced by the New York City based record label Putumayo World Music, was nominated for a Grammy Award in the Best World Music Album category. She worked closely with Graca Machel-Mandela, the South African first lady, advocating for children suffering from HIV/AIDS, child soldiers, and the physically handicapped. She established the Makeba Centre for Girls, a home for orphans, described in an obituary as her most personal project. She also took part in the 2002 documentary Amandla!: A Revolution in Four-Part Harmony, which examined the struggles of black South Africans against apartheid through the music of the period. Makeba's second autobiography, Makeba: The Miriam Makeba Story, was published in 2004. In 2005 she announced that she would retire and began a farewell tour, but despite having osteoarthritis, continued to perform until her death. During this period, her grandchildren Nelson Lumumba Lee and Zenzi Lee, and her great-grandchild Lindelani, occasionally joined her performances.  On 9 November 2008, Makeba fell ill during a concert in Castel Volturno, near Caserta, Italy. The concert had been organised to support the writer Roberto Saviano in his stand against the Camorra, a criminal organisation active in the Campania region. She suffered a heart attack after singing her hit song "Pata Pata", and was taken to the Pineta Grande clinic, where doctors were unable to revive her.
