Year 1970 (MCMLXX) was a common year starting on Thursday (link will display the full calendar) of the Gregorian calendar. It is the Unix epoch time and it was also the first year of the 1970s.

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".

James Vernon Taylor (born March 12, 1948) is an American singer-songwriter and guitarist. A five-time Grammy Award winner, Taylor was inducted into the Rock & Roll Hall of Fame in 2000.

Taylor achieved his major breakthrough in 1970 with the #3 single "Fire and Rain" and had his first #1 hit the following year with "You've Got a Friend", a recording of Carole King's classic song. His 1976 Greatest Hits album was certified Diamond and has sold 12 million US copies. Following his 1977 album, JT, he has retained a large audience over the decades. His commercial achievements declined slightly until a big resurgence during the late 1990s and 2000s, when some of his best-selling and most-awarded albums (including Hourglass, October Road and Covers) were released.

James Taylor was born at Massachusetts General Hospital in Boston, Massachusetts, on March 12, 1948, where his father, Isaac M. Taylor, was a resident physician. His father was from a well-off family of Southern Scottish ancestry. His mother, the former Gertrude Woodard, had studied singing with Marie Sundelius at the New England Conservatory of Music and was an aspiring opera singer before the couple's marriage in 1946. James was the second of five children, the others being Alex (1947-1993), Kate (born 1949), Livingston (born 1950), and Hugh (born 1952).

Mark Neary Donohue, Jr. (March 18, 1937 – August 19, 1975), nicknamed "Captain Nice", was an American racecar driver known for his ability to set up his own race car as well as driving it to victories. Donohue is probably best known as the driver of the 1500+ bhp “Can-Am Killer” Porsche 917-30 and as the winner of the 1972 Indianapolis 500. Cars that Donohue raced include: AMC Javelin, AMC Matador, Chevrolet Camaro, Eagle-Offy, Elva Courier, Ford GT-40 MK IV, Ferrari 250LM, Ferrari 512, Lola T70, Lola T330, Lotus 20, McLaren M16, Porsche 911, Porsche 917/10, Porsche 917/30, Shelby Cobra, and Shelby Mustang GT350R.

Donohue was born in Haddon Township, New Jersey and grew up in Summit, New Jersey. He attended the Pingry School in Hillside, New Jersey and upon graduation, he entered Brown University in Providence, Rhode Island. Donohue was graduated in 1959 with a bachelors degree in mechanical engineering and began racing his 1957 Corvette casually at the age of twenty-two. He won his first event, a Belknap County, New Hampshire hillclimb, in that car. Eventually, through networking with various SCCA drivers, he was introduced to a well-known retired race driver and as-yet unsuccessful race team owner named Roger Penske.

Pier Paolo Pasolini (March 5, 1922 – November 2, 1975) was an Italian film director, poet, writer and intellectual. Pasolini distinguished himself as a poet, journalist, philosopher, linguist, novelist, playwright, filmmaker, newspaper and magazine columnist, actor, painter and political figure. He demonstrated a unique and extraordinary cultural versatility, becoming a highly controversial figure in the process.

Pasolini was born in Bologna, traditionally one of the most leftist of Italian cities. He was the son of a lieutenant of the Italian Army, Carlo Alberto, who had become famous for saving Benito Mussolini's life during Anteo Zamboni's assassination attempt, and subsequently married an elementary school teacher, Susanna Colussi, in 1921. Pasolini was born in 1922 and was named after his paternal uncle. His family moved to Conegliano in 1923 and, two years later, to Belluno, where another son, Guidalberto, was born. In 1926, Pasolini's father was arrested for gambling debts, and his mother took the children to her family's house in Casarsa della Delizia, in the Friuli region.
