Question: David Michael Letterman (born April 12, 1947) is an American television host, comedian, writer, and producer. He hosted a late night television talk show for 33 years, beginning with the February 1, 1982, debut of Late Night with David Letterman on NBC, and ending with the May 20, 2015, broadcast of Late Show with David Letterman on CBS. In total, Letterman hosted 6,028 episodes of Late Night and Late Show, surpassing friend and mentor Johnny Carson as the longest-serving late night talk show host in American television history. In 1996 Letterman was ranked 45th on TV Guide's 50 Greatest TV Stars of All Time.

In 1975, encouraged by his then-wife Michelle and several of his Sigma Chi fraternity brothers, Letterman moved to Los Angeles, with hope of becoming a comedy writer. He and Michelle packed their belongings in his pickup truck and headed west. As of 2012, he still owned the truck. In Los Angeles, he began performing comedy at The Comedy Store. Jimmie Walker saw him on stage; with an endorsement from George Miller, Letterman joined a group of comedians whom Walker hired to write jokes for his stand-up act, a group that at various times would also include Jay Leno, Paul Mooney, Robert Schimmel, Richard Jeni, Louie Anderson, Elayne Boosler, Byron Allen, Jack Handey, and Steve Oedekerk. By the summer of 1977, Letterman was a writer and regular on the six-week summer series The Starland Vocal Band Show, broadcast on CBS. He hosted a 1977 pilot for a game show entitled The Riddlers (that was never picked up), and co-starred in the Barry Levinson-produced comedy special Peeping Times that aired in January 1978. Later that year, Letterman was a cast member on Mary Tyler Moore's variety show, Mary. Letterman made a guest appearance on Mork & Mindy (as a parody of EST leader Werner Erhard) and appearances on game shows such as The $20,000 Pyramid, The Gong Show, Hollywood Squares, Password Plus and Liar's Club, as well as the Canadian cooking show Celebrity Cooks (November 1977), talk shows such as 90 Minutes Live (February 24 and April 14, 1978), and The Mike Douglas Show (April 3, 1979 and February 7, 1980). He was also screen tested for the lead role in the 1980 film Airplane!, a role that eventually went to Robert Hays. His dry, sarcastic humor caught the attention of scouts for The Tonight Show Starring Johnny Carson, and Letterman was soon a regular guest on the show. Letterman became a favorite of Carson and was a regular guest host for the show beginning in 1978. Letterman credits Carson as the person who influenced his career the most.

Problem: Florence Leontine Mary Welch was born in Camberwell, London on 28 August 1986. Her father is Nick Russell Welch, an advertising executive. Her mother, Evelyn Welch (nee Evelyn Kathleen Samuels), is an American emigrant from New York City who was educated at Harvard University and the Warburg Institute, University of London. Evelyn is currently Professor of Renaissance Studies and Vice-Principal for Arts and Sciences at King's College London.

According to Welch, the band name "Florence + the Machine" had "started off as a private joke that got out of hand. I made music with my friend, who we called Isabella Machine, to which I was Florence Robot. When I was about an hour away from my first gig, I still didn't have a name, so I thought 'Okay, I'll be Florence Robot/Isa Machine', before realising that name was so long it'd drive me mad". In 2006, Welch's performances with Isabella Summers in small London venues under the joint name Florence Robot/Isa Machine began to attract notice. In 2007, Welch recorded with a band named Ashok, who released an album titled Plans on the Filthy Lucre/About Records label. This album included the earliest version of her later hit "Kiss with a Fist", which at this point was titled "Happy Slap". Florence and the Machine released their debut album Lungs in the United Kingdom on 6 July 2009. The album was officially launched with a set at the Rivoli Ballroom in Brockley, South East London. It peaked at number one in the UK and number two in Ireland. As of 6 August 2009, the album had sold over 100,000 copies in the UK and by 10 August it had been at number two for five consecutive weeks. Following its 25 July 2009 release for download in the United States, the album debuted at number seventeen on the Billboard Heatseekers Albums chart, ultimately peaking at number one. The album was released physically in the US on 20 October by Universal Republic. The album was produced by James Ford, Paul Epworth, Steve Mackey and Charlie Hugall. Welch contributed vocals to David Byrne and Fatboy Slim's 2010 album Here Lies Love, an album about Imelda Marcos. As of January 2011, Welch was working with Drake on material slated for his upcoming album. On 27 February 2011, Welch replaced pregnant Dido and sang her portion of Best Original Song nominee "If I Rise" (from 127 Hours) with A. R. Rahman at the 83rd Academy Awards.
