John R. "Johnny" Cash (February 26, 1932 – September 12, 2003), was an American singer-songwriter, actor, and author, who has been called one of the most influential musicians of the 20th century. Although he is primarily remembered as a country music icon, his songs and sound spanned many other genres including rockabilly and rock and roll—especially early in his career—as well as blues, folk, and gospel. This crossover appeal led to Cash being inducted in the Country Music Hall of Fame, the Rock and Roll Hall of Fame, and Gospel Music Hall of Fame.

Cash was known for his deep, distinctive bass-baritone voice; for the "boom-chicka-boom" sound of his Tennessee Three backing band; for his rebelliousness, coupled with an increasingly somber and humble demeanor; for providing free concerts inside prison walls; and for his dark performance clothing, which earned him the nickname "The Man in Black". He traditionally started his concerts by saying, "Hello, I'm Johnny Cash." and usually following it up with his standard "Folsom Prison Blues".

Roy Rogers, born Leonard Franklin Slye (November 5, 1911 – July 6, 1998), was an American singer and cowboy actor, one of the most heavily marketed and merchandised stars of his era, as well as being the namesake of the Roy Rogers Restaurants franchised chain. He and his wife Dale Evans, his golden palomino, Trigger, and his German Shepherd dog, Bullet, were featured in more than 100 movies and The Roy Rogers Show. The show ran on radio for nine years before moving to television from 1951 through 1957. His productions usually featured a sidekick, often either Pat Brady (who drove a Jeep called "Nellybelle"), Andy Devine, or the crotchety George "Gabby" Hayes. Rogers's nickname was "King of the Cowboys". Evans's nickname was "Queen of the West."

Leonard Franklin Slye was born to Andrew ("Andy") and Mattie (Womack) Slye in Cincinnati, Ohio, where his family lived in a tenement building on 2nd Street. (Riverfront Stadium was constructed at this location in 1970 and Leonard would later joke that he had been born at second base.) Dissatisfied with his job and city life, Andy Slye and his brother Will built a 12-by-50-foot houseboat from salvage lumber, and, in July 1912, the Slye family floated up the Ohio River towards Portsmouth, Ohio. Desiring a more stable existence in Portsmouth, the Slyes purchased land on which to build a home, but the flood of 1913 allowed them to move the houseboat to their property and continue living in it on dry land.

Jon Stewart (born Jonathan Stuart Leibowitz; November 28, 1962) is an American political satirist, writer, television host, actor, media critic and stand-up comedian. He is widely known as host of The Daily Show, a satirical news program that airs on Comedy Central.

Stewart started as a stand-up comedian, but branched into television as host of Short Attention Span Theater for Comedy Central. He went on to host his own show on MTV, called The Jon Stewart Show, and then hosted another show on MTV called You Wrote It, You Watch It. He has also had several film roles as an actor. Stewart became the host of The Daily Show on Comedy Central in early 1999. He is also a writer and co-executive-producer of the show. After Stewart joined, The Daily Show steadily gained popularity and critical acclaim, resulting in his sixteen Emmy Awards.

Stewart has gained acclaim as an acerbic, satirical critic of personality-driven media shows, in particular those of the US media networks such as CNN, Fox News Channel, and MSNBC. Critics say Stewart benefits from a double standard: he critiques other news shows from the safe, removed position of his "fake news" desk. Stewart agrees, saying that neither his show nor his channel purports to be anything other than satire and comedy. In spite of its self-professed entertainment mandate, The Daily Show has been nominated for news and journalism awards. Stewart hosted the 78th and 80th Academy Awards. He is the co-author of America (The Book): A Citizen's Guide to Democracy Inaction, which was one of the best-selling books in the U.S. in 2004 and Earth (The Book): A Visitor's Guide to the Human Race released in 2010.
