Howard Andrew "Andy" Williams (born December 3, 1927) is an American singer who has recorded 18 Gold- and three Platinum-certified albums. He hosted The Andy Williams Show, a TV variety show, from 1962 to 1971, as well as numerous television specials, and owns the Moon River Theatre in Branson, Missouri named after the song "Moon River", with which he is closely identified.

Williams was born in Wall Lake, Iowa, the son of Jay Emerson and Florence (née Finley) Williams. He first performed in a children's choir at the local Presbyterian church. Williams and his three older brothers Bob, Don, and Dick formed the Williams Brothers quartet in late 1938, and they performed on radio in the Midwest, first at WHO in Des Moines, Iowa, and later at WLS in Chicago and WLW in Cincinnati. Williams graduated from Western Hills High School in Cincinnati and his brother was engaged to Gene Ingram's car-pool partner, Peggy. The Williams Brothers appeared with Bing Crosby on the hit record "Swinging on a Star" (1944). They appeared in 4 musical films: Janie (1944), Kansas City Kitty (1944), Something in the Wind (1947) and Ladies' Man (1947). This led to a nightclub act with entertainer Kay Thompson from 1947 to 1951.

David Andrew "Andy" Samberg (born August 18, 1978) is an American actor, comedian, rapper, and writer best known as a member of the comedy group The Lonely Island and as a cast member on Saturday Night Live from 2005 to 2012. On Saturday Night Live, he and The Lonely Island have been credited with popularizing the Emmy-winning SNL Digital Shorts, the comical short films and music videos starring Samberg and other members of the SNL cast. As a film actor, Samberg has appeared in Hot Rod; Space Chimps; Nick and Norah's Infinite Playlist; I Love You, Man; Cloudy with a Chance of Meatballs; Friends with Benefits; and What's Your Number?

Samberg was born in Mill Valley California, the son of Joe Samberg, a photographer, and Margi (née Marrow), an elementary school teacher who taught at Old Mill School. Samberg also has two sisters, Johanna and Darrow. He was raised in a Jewish household. His maternal grandfather, Alfred J. Marrow, served as the executive chair of the American Jewish Congress, although Samberg describes himself as "not particularly religious." Samberg discovered Saturday Night Live as a child while sneaking past his parents to watch professional wrestling on television. He became "obsessed" with the show, and his devotion to comedy became frustrating to teachers who felt he was unfocused on his schoolwork.

David Michael Letterman (born April 12, 1947) is an American television host and comedian. He hosts the late night television talk show, Late Show with David Letterman, broadcast on CBS. Letterman has been a fixture on late night television since the 1982 debut of Late Night with David Letterman on NBC.

Letterman is also a television and film producer. His company Worldwide Pants produces his show as well as its network follow-up The Late Late Show with Craig Ferguson. Worldwide Pants has also produced several prime-time comedies, the most successful of which was Everybody Loves Raymond, currently in syndication.

In 1996, David Letterman was ranked #45 on TV Guide's 50 Greatest TV Stars of All Time.

Letterman was born in Indianapolis, Indiana. His father, Harry Joseph Letterman (April 1915 – February 1973), was a florist of British descent; his mother Dorothy Letterman (née Hofert, now Dorothy Mengering), a Presbyterian church secretary of German descent, is an occasional figure on the show, usually at holidays and birthdays.

Andy McKee (born April 4, 1979, in Topeka, Kansas) is an American fingerstyle guitar player, currently signed to the American record label Razor & Tie.

His style of playing and his compositions have earned him a considerable international fanbase. In late 2006, a live performance of his signature song "Drifting" became a Featured Video on YouTube and MySpace, achieving over 48 million views on the former to date and remaining one of its highest-rated music clips. A handful of McKee's other songs have experienced notable success on YouTube, such as "Rylynn" with over 22 million views. Similarly, McKee's cover of "Africa" reached over 9 million views before suddenly being removed by Candyrat Records.

McKee played his first guitar, an Aria nylon string bought by his father, at age 13. Initially underwhelmed by his guitar lessons, McKee's electric guitar-playing cousin inspired him to continue learning, taking him out for his 16th birthday to see a guitarist named Preston Reed perform live at a clinic. McKee later bought an instructional videotape from Reed and began to learn more complex guitar techniques from it, also earning his GED that year in order to quit attending high school. He began to draw influence from guitarists such as Michael Hedges, Billy McLaughlin, Pat Kirtley, and from Passion Session by Don Ross, as he continued studying the instrument on his own.
