Background: Woodrow Wilson Guthrie (; July 14, 1912 - October 3, 1967) was an American singer-songwriter, one of the most significant figures in American folk music; his songs, including social justice songs, such as "This Land Is Your Land", have inspired several generations both politically and musically. He wrote hundreds of political, folk, and children's songs, along with ballads and improvised works. His album of songs about the Dust Bowl period, Dust Bowl Ballads, is included on Mojo magazine's 100 Records That Changed The World. Many of his recorded songs are archived in the Library of Congress.
Context: During the Dust Bowl period, Guthrie joined the thousands of Okies who were migrating to California looking for work, leaving his wife and children in Texas. Many of his songs are concerned with the conditions faced by these working-class people.  During the late part of that decade, he achieved fame with radio partner Maxine "Lefty Lou" Crissman as a broadcast performer of commercial hillbilly music and traditional folk music. Guthrie was making enough money to send for his family, who were still living in Texas. While appearing on the commercial radio station KFVD, owned by a populist-minded New Deal Democrat, Frank W. Burke, Guthrie began to write and perform some of the protest songs that would eventually appear on Dust Bowl Ballads.  While at KFVD, Guthrie met newscaster Ed Robbin. Robbin was impressed with a song Guthrie wrote about political activist Thomas Mooney, believed by many to be wrongly convicted in a case that was a cause celebre of the time. Robbin, who became Guthrie's political mentor, introduced Guthrie to socialists and Communists in Southern California, including Will Geer (who, in turn, introduced Guthrie to John Steinbeck). Robbin remained Guthrie's lifelong friend, and helped Guthrie book benefit performances in the Communist circles in Southern California. Notwithstanding Guthrie's later claim that "the best thing that I did in 1936 was to sign up with the Communist Party", he was never a member of the party. He was noted as a fellow traveler--an outsider who agreed with the platform of the party while not subject to party discipline. Guthrie wrote a column for the Communist newspaper, People's World. The column, titled "Woody Sez", appeared a total of 174 times from May 1939 to January 1940. "Woody Sez" was not explicitly political, but was about current events as observed by Guthrie. He wrote the columns in an exaggerated hillbilly dialect and usually included a small comic; they were published as a collection after Guthrie's death. Steve Earle said of Guthrie, "I don't think of Woody Guthrie as a political writer. He was a writer who lived in very political times."  With the outbreak of World War II and the non-aggression pact the Soviet Union had signed with Germany in 1939, the owners of KFVD radio did not want its staff "spinning apologia" for the Soviet Union. Both Robbin and Guthrie left the station. Without the daily radio show, his prospects for employment diminished, and Guthrie and his family returned to Pampa, Texas. Although Mary Guthrie was happy to return to Texas, Guthrie preferred to accept Will Geer's invitation to New York City and headed east.
Question: Did he marry any one?
Answer: Ed Robbin.

Background: David Paradine Frost was born in Tenterden, Kent, on 7 April 1939, the son of a Methodist minister of Huguenot descent, the Rev. Wilfred John "W. J." Paradine Frost, and his wife, Mona (Aldrich); he had two elder sisters. While living in Gillingham, Kent, he was taught in the Bible class of the Sunday school at his father's church (Byron Road Methodist) by David Gilmore Harvey, and subsequently started training as a Methodist local preacher, which he did not complete. Frost attended Barnsole Road Primary School in Gillingham, St Hugh's School, Woodhall Spa, Gillingham Grammar School and finally - while residing in Raunds - Wellingborough Grammar School. Throughout his school years he was an avid football and cricket player, and was offered a contract with Nottingham Forest F.C.
Context: Frost was one of the "Famous Five" who launched TV-am in February 1983 but, like LWT in the late 1960s, the station began with an unsustainable "highbrow" approach. Frost remained a presenter after restructuring. Frost on Sunday began in September 1983 and continued until the station lost its franchise at the end of 1992. Frost had been part of an unsuccessful consortium, CPV-TV, with Richard Branson and other interests, which had attempted to acquire three ITV contractor franchises prior to the changes made by the Independent Television Commission in 1991. After transferring from ITV, his Sunday morning interview programme Breakfast with Frost ran on the BBC from January 1993 until 29 May 2005. For a time it ran on BSB before moving to BBC 1.  Frost hosted Through the Keyhole, which ran on several UK channels from 1987 until 2008 and also featured Loyd Grossman. Produced by his own production company, the programme was first shown in prime time and on daytime television in its later years.  Frost worked for Al Jazeera English, presenting a live weekly hour-long current affairs programme, Frost Over The World, which started when the network launched in November 2006. The programme regularly made headlines with interviewees such as Tony Blair, President Omar al-Bashir of Sudan, Prime Minister Benazir Bhutto of Pakistan and President Daniel Ortega of Nicaragua. The programme was produced by the former Question Time editor and Independent on Sunday journalist Charlie Courtauld. Frost was one of the first to interview the man who authored the Fatwa on Terrorism, Muhammad Tahir-ul-Qadri.  During his career as a broadcaster Frost became one of Concorde's most frequent fliers, having flown between London and New York an average of 20 times per year for 20 years.  In 2007, Frost hosted a discussion with Libya's leader Muammar Gaddafi as part of the Monitor Group's involvement in the country. In June 2010, Frost presented Frost on Satire, an hour-long BBC Four documentary looking at the history of television satire.
