input: Little is known about Johnson's life and musical career, although his recordings are well documented. In October 1936, Johnson auditioned for music store owner and sometime talent scout H. C. Speir in Jackson, Mississippi; Speir passed on Johnson's contact information to Ernie Oertle, who was a representative for ARC Records. After a second audition, Oertle arranged for Johnson to travel to San Antonio, Texas, for a recording session. Johnson recorded 22 songs for ARC over three days from November 23 to 27, 1936. During the first session, he recorded his most commercially appealing songs. They mostly represented his original pieces and reflected current, piano-influenced musical trends. The songs include "Terraplane Blues" (his first single and most popular record) along with "Sweet Home Chicago" and "I Believe I'll Dust My Broom", which became blues standards after others recorded them.  A second and third recording date took place in San Antonio after a two-day break. Johnson reached back into his long-standing repertoire for songs to record. The material reflects the styles of country blues performers Charley Patton and Son House, who influenced Johnson in his youth. The songs are among Johnson's most heartfelt and forceful, and music historian Ted Gioia sees a shift in the lyrical themes:  At the close of the San Antonio session, the darker, more apocalyptic side of Johnson's work emerges ... [he] evokes the themes of damnation and redemption, darkness and light ... glimpses into the musician's inner life, and all its attendant turmoils.  "Cross Road Blues" was recorded during Johnson's third session in San Antonio, on Friday November 27, 1936. The sessions continued at an improvised studio in Room 414 at the Gunter Hotel. ARC producers Art Satherley and Don Law supervised the recording and used a portable disc cutting machine. It is unknown what input, if any, they had into Johnson's selection of material to record or how to present it. Two similar takes of the song were recorded.

Problem: Background: Mwai Kibaki, C.G.H. (born 15 November 1931) is a Kenyan politician who was the third President of Kenya, serving from December 2002 until April 2013. Kibaki was previously Vice-President of Kenya for ten years from 1978 to 1988 under President Daniel arap Moi. He also held cabinet ministerial positions in the Kenyatta and Moi governments, including time as minister for Finance (1969-1981) under Kenyatta, and Minister for Home Affairs (1982-1988) and Minister for Health (1988-1991) under Moi. Kibaki served as an opposition Member of Parliament from 1992 to 2002.
Context: President Kibaki was married to Lucy Muthoni from 1961 until her death in 2016. They have four children: Judy Wanjiku, Jimmy Kibaki, David Kagai, and Tony Githinji. They also have four grandchildren: Joy Jamie Marie, Mwai Junior, Krystinaa Muthoni. Jimmy Kibaki did have, so far unsuccessful, designs to be his father's political heir.  In 2004, the media reported that Kibaki has a second spouse, whom he allegedly married under customary law, Mary Wambui, and a daughter, Wangui Mwai. State House in response released an unsigned statement that Kibaki's only immediate family at the time was his then wife, Lucy, and their four children. In 2009, Kibaki, with Lucy in close attendance, held an odd press conference to re-state publicly that he only has one wife. The matter of Kibaki's alleged mistress, and his wife's usually dramatic public reactions thereto, provided an embarrassing side-show during his presidency, with the Washington Post terming the entire scandal as a "new Kenyan soap opera".  Ms. Wambui, the rather popular "other woman", who enjoyed the state trappings of a Presidential spouse and became a powerful and wealthy business-woman during the Kibaki Presidency, frequently drove Lucy into episodes of highly embarrassing very publicly displayed rage. Ms. Wambui, despite opposition from Kibaki's family, led publicly by Kibaki's son, Jimmy, and despite Kibaki's public endorsement and campaign for her opponent, succeeded Kibaki as Member of Parliament for Othaya in the 2013 General Election. In December 2014, Senator Bonny Khalwale stated on KTN's Jeff Koinange Live that President Kibaki had introduced Wambui as his wife.  Kibaki enjoys playing golf and is a member of the Muthaiga Golf Club. He is a practicing and a very committed member of the Roman Catholic Church and attends Consolata Shrines Catholic Church in Nairobi every Sunday at noon.  On 21 August 2016, Kibaki, who was ill, was taken to Karen Hospital and later flown to South Africa for specialized treatment.

Question: Cancer Bats are a Canadian hardcore punk band from Toronto, Ontario. They have released five studio albums and six extended plays. The band is composed of vocalist Liam Cormier, guitarist Scott Middleton, drummer Mike Peters and bassist Jaye R. Schwarzer. Cancer Bats take a wide variety of influences from heavy metal subgenres and fuse them into hardcore and punk rock, and also include elements of Southern rock.

Cancer Bats was founded in May 2004 by singer Liam Cormier and guitarist Scott Middleton, a former member of Toronto heavy metal band At the Mercy of Inspiration. The two wanted to form a project that combined their favorite parts of bands like Entombed, Refused, Black Flag, Led Zeppelin and Down, among others. The lineup was completed with the addition of Andrew McCracken on bass and Joel Bath on drums, with Cormier moving to vocals. The four-piece wrote and recorded songs for a self-released demo that saw light in January 2005, and led to Canadian independent record label Distort Entertainment signing the band.  The story is that the band considered the names Cancer Bats and Pneumonia Hawk after deciding that a combination of illness and animal name would give the best band name. Soon after, Mike Peters replaced Bath on the drums and the band began playing throughout Southern Ontario, playing live shows with bands like Billy Talent, Every Time I Die, Nora, Alexisonfire, Haste the Day, It Dies Today, Bane, Comeback Kid, Buried Inside, Attack in Black, Misery Signals, This Is Hell, Rise Against, The Bronx and Gallows.  On June 2, 2006, the band took part in a short interview and then played a free CD release show at The Edge 102.1 (CFNY-FM) and then on June 6 Birthing the Giant was released into major record stores. The album includes guest vocals by George Pettit of Alexisonfire. On June 7, 2006 they hosted All Things Rock, a show on MTV Canada, and had their own video played at the end of the show.
