Richard Lee Petty (born July 2, 1937) is a former NASCAR driver who raced in the Strictly Stock/Grand National Era and the NASCAR Winston Cup Series. "The King", as he is nicknamed, is most well known for winning the NASCAR Championship seven times (Dale Earnhardt is the only other driver to accomplish this feat), winning a record 200 races during his career, winning the Daytona 500 a record seven times, and winning a record 27 races (ten of them consecutively) in the 1967 season alone. (A 1972 rule change eliminated races under 250 miles (400 km) in length, reducing the schedule to 30 [now 36] races.) Petty is widely considered one of the greatest NASCAR drivers of all time and is one of the most respected figures in motorsports as a whole. He also collected a record number of poles (127) and over 700 top-ten finishes in his 1,185 starts, including 513 consecutive starts from 1971–1989. Petty is a member of the inaugural class of the NASCAR Hall of Fame. He was inducted into the Hall in 2010.

Janis Lyn Joplin (January 19, 1943 – October 4, 1970) was an American singer and songwriter from Port Arthur, Texas. As a youth Joplin was ridiculed by her fellow students due to her unconventional appearance and personal beliefs. She later sang about her experience at school through her song "Ego Rock". Early in her life, Joplin cultivated a rebellious and unconventional lifestyle, becoming a beatnik poet. She began her singing career as a folk and blues singer in San Francisco, playing clubs and bars with her guitar and auto-harp.

Joplin first rose to prominence in the late 1960s as the lead singer of the psychedelic-acid rock band Big Brother and the Holding Company, and later as a solo artist with her more soulful and bluesy backing groups, The Kozmic Blues Band and The Full Tilt Boogie Band. She was one of the more popular acts at the Monterey Pop Festival and later became one of the major attractions to the Woodstock festival and the Festival Express train tour.

Janis Joplin only charted five singles in her life but her hits and other popular songs from throughout her short four year career include "Down On Me", "Bye, Bye Baby", "Coo Coo", "Summertime", "Piece of My Heart", "Turtle Blues", "Ball 'n' Chain", "Try (Just A Little Bit Harder)", "Maybe", "To Love Somebody", "Kozmic Blues", "Work Me, Lord", "Move Over", "Cry Baby", "A Woman Left Lonely" "Get It While You Can", "My Baby", "Trust Me", "Mercedes Benz", "One Night Stand", "Raise Your Hand" and her only number one hit, "Me and Bobby McGee".

Charles Bronson (November 3, 1921 – August 30, 2003), born Charles Dennis Buchinsky was an American actor, of Polish and Lithuanian background, best known for such films as Once Upon a Time in the West, The Magnificent Seven, The Dirty Dozen, The Great Escape, Rider on the Rain, The Mechanic, and the popular Death Wish series. He was often cast in the role of a police officer or gunfighter, often in revenge-oriented plot lines. During his career, Bronson had a long-term partnership with directors Michael Winner and J. Lee Thompson.

Bronson was born Charles Dennis Buchinsky (or Buchinskas) in Ehrenfeld, Pennsylvania, in the Allegheny Mountain Coal region north of Johnstown. During the McCarthy hearings, he changed his last name to Bronson, fearing that Buchinsky sounded "too Russian".

He was one of 15 children born to a Lithuanian immigrant father of Lipka Tatar ancestry, and a Lithuanian-American mother. His father hailed from the town of Druskininkai (or Druskienniki). His mother, Mary Valinsky, whose parents were from the Lithuania was born in the anthracite coal mining town of Tamaqua, Pennsylvania.

Marion Mitchell Morrison (born Marion Robert Morrison; May 26, 1907 – June 11, 1979), better known by his stage name John Wayne, was an American film actor, director and producer. An Academy Award-winner, Wayne was among the top box office draws for three decades, and was named the all-time top money-making star. An enduring American icon, he epitomized rugged masculinity and is famous for his demeanor, including his distinctive calm voice, walk, and height.

Wayne was born in Winterset, Iowa but his family relocated to the greater Los Angeles area when he was four years old. He found work at local film studios when he lost his football scholarship to USC as a result of a bodysurfing accident. Initially working for the Fox Film Corporation, he mostly appeared in small bit parts. His acting breakthrough came in 1939 with John Ford's Stagecoach, making him an instant star. Wayne would go on to star in 142 pictures, primarily typecast in Western films.

Among his best known films are The Quiet Man (1952), which follows him as an Irish-American boxer and his love affair with a fiery spinster played by Maureen O'Hara; The Searchers (1956), in which he plays a Civil War veteran who seeks out his abducted niece; Rio Bravo (1959), playing a Sheriff with Dean Martin; True Grit (1969), playing a humorous U.S. Marshal who sets out to avenge a man's death in the role that won Wayne an Academy Award; and The Shootist (1976), his final screen performance in which he plays an aging gunslinger battling cancer.
