Problem: Stanley Kirk Burrell (born March 30, 1962), better known by his stage name MC Hammer (or simply Hammer), is an American hip hop recording artist, dancer, record producer and entrepreneur. He had his greatest commercial success and popularity from the late 1980s, until the early 1990s. Remembered for his rapid rise to fame, Hammer is known for hit records (such as "U Can't Touch This" and "2 Legit 2 Quit"), flashy dance movements, choreography and eponymous Hammer pants. A multi-award winner, M.C. Hammer is considered a "forefather/pioneer" and innovator of pop rap (incorporating elements of freestyle music), and is the first hip hop artist to achieve diamond status for an album.

In the mid-1980s while rapping in small venues and after a record deal went sour, Hammer borrowed US$20,000 each from former Oakland A's players Mike Davis and Dwayne Murphy to start a record label business called Bust It Productions. He kept the company going by selling records from his basement and car. Bust It spawned Bustin' Records, the independent label of which Hammer was CEO. Together, the companies had more than 100 employees. Recording singles and selling them out of the trunk of his car, he marketed himself relentlessly. Coupled with his dance abilities, Hammer's style was unique at the time. Now billing himself as "M.C. Hammer", he recorded his debut album, Feel My Power, which was produced between 1986 and 1987 and released independently in 1987 on his Oaktown Records label (Bustin'). It was produced by Felton Pilate (of Con Funk Shun), and sold over 60,000 copies and was being distributed by City Hall Records. In the spring of 1988, a 107.7 KSOL Radio DJ Tony Valera played the track "Let's Get It Started" in his mix-shows--a song in which he declared he was "second to none, from Doug E. Fresh, LL Cool J, or DJ Run"--after which the track began to gain popularity in clubs. (He would continue to call out other East Coast rappers in future projects as well.) Hammer also released a single called "Ring 'Em", and largely on the strength of tireless street marketing by Hammer and his wife, plus continued radio mix-show play, it achieved considerable popularity at dance clubs in the San Francisco Bay Area. Heartened by his rising prospects, Hammer launched into seven-day-a-week rehearsals with the growing troupe of dancers, musicians, and backup vocalists he had hired. It was Hammer's stage show, and his infectious stage presence, that led to his big break in 1988 while performing in an Oakland club. There he impressed a record executive who "didn't know who he was, but knew he was somebody", according to the New Rolling Stone Encyclopedia of Rock & Roll. M.C.Hammer had received several offers from major record labels before (which he initially declined due to his personal success), but after the successful release of this independent album and elaborate live dance show amazed the Capitol Records executive, Hammer agreed to sign a record deal soon after. Hammer took home a US$1,750,000 advance and a multi-album contract. It didn't take long for Capitol to recoup its investment.

Were there any hit singles?

Answer with quotes: "Let's Get It Started"

Problem: David Gaub McCullough (; born July 7, 1933) is an American author, narrator, historian, and lecturer. He is a two-time winner of the Pulitzer Prize and the National Book Award and a recipient of the Presidential Medal of Freedom, the United States' highest civilian award. Born and raised in Pittsburgh, McCullough earned a degree in English literature from Yale University.

McCullough was born in the Point Breeze neighborhood of Pittsburgh, Pennsylvania, the son of Ruth (nee Rankin) and Christian Hax McCullough. He is of Scots-Irish descent. He was educated at Linden Avenue Grade School and Shady Side Academy, in his hometown of Pittsburgh. One of four sons, McCullough had a "marvelous" childhood with a wide range of interests, including sports and drawing cartoons. McCullough's parents and his grandmother, who read to him often, introduced him to books at an early age. His parents often talked about history, a topic he says should be discussed more often. McCullough "loved school, every day"; he contemplated many career choices, ranging from architect, actor, painter, writer, to lawyer, and contemplated attending medical school for a time. In 1951, McCullough began attending Yale University. He said that it was a "privilege" to study English at Yale because of faculty members such as John O'Hara, John Hersey, Robert Penn Warren, and Brendan Gill. McCullough occasionally ate lunch with the Pulitzer Prize-winning novelist and playwright Thornton Wilder. Wilder, says McCullough, taught him that a competent writer maintains "an air of freedom" in the storyline, so that a reader will not anticipate the outcome, even if the book is non-fiction. While at Yale, he became a member of Skull and Bones. He served apprenticeships at Time, Life, the United States Information Agency, and American Heritage, where he enjoyed research. "Once I discovered the endless fascination of doing the research and of doing the writing, I knew I had found what I wanted to do in my life." While attending Yale, McCullough studied Arts and earned his bachelor's degree in English, with the intention of becoming a fiction writer or playwright. He graduated with honors in English literature (1955).
