Rosanne Cash (born May 24, 1955) is an American singer-songwriter and author. She is the eldest daughter of country music icon Johnny Cash and his first wife, Vivian Liberto Cash Distin.

Although Cash is often classified as a country artist, her music draws on many genres, including folk, pop, rock and blues. In the 1980s, she had a string of chart-topping singles, which crossed musical genres and landed on both C&W and Top 100 charts, the most commercially successful being her 1981 breakthrough hit "Seven Year Ache", which topped the U.S. country singles charts and reached the Top 30 on the U.S. pop singles charts. In 1990, Cash released Interiors, a spare, introspective album which signaled a break from her pop country past. The following year Cash ended her marriage and moved from Nashville to New York City, where she continues to write, record and perform. Since 1991 she has released five albums, written two books and edited a collection of short stories. Her fiction and essays have been published in The New York Times, Rolling Stone, The Oxford-American, New York Magazine, and various other periodicals and collections.

John Winston Ono Lennon, MBE (9 October 1940 – 8 December 1980) was an English musician and singer-songwriter who rose to worldwide fame as one of the founder members of The Beatles, one of the most commercially successful and critically acclaimed acts in the history of popular music. Together with Paul McCartney, he formed one of the most celebrated songwriting partnerships of the 20th century.

Born and raised in Liverpool, Lennon became involved as a teenager in the skiffle craze; his first band, The Quarrymen, evolved into The Beatles in 1960. As the group disintegrated towards the end of the decade, Lennon embarked on a solo career that produced the critically acclaimed albums John Lennon/Plastic Ono Band and Imagine, and iconic songs such as "Give Peace a Chance" and "Imagine". After his marriage to Yoko Ono in 1969, he changed his name to John Ono Lennon. Lennon disengaged himself from the music business in 1975 to devote time to raising his infant son Sean, but re-emerged with Ono in 1980 with the new album Double Fantasy. He was murdered three weeks after its release.
