"Imagine" is a song written and performed by English musician John Lennon. It was released as a single from his album Imagine in 1971, and was released as a single in the United Kingdom in 1975 in conjunction with the album Shaved Fish. It was inspired by a poem from Yoko Ono's 1964 book Grapefruit.

The song received a Grammy Hall of Fame Award and is in the Rock and Roll Hall of Fame's 500 Songs that Shaped Rock and Roll; it was ranked the 3rd greatest song of all time by Rolling Stone in its "The 500 Greatest Songs of All Time".

The song's central theme was inspired by "Cloud Piece", a three-line instructional poem that appeared in Ono's 1964 book Grapefruit. The words were reproduced on the back cover of the Imagine album.

In a 1980 interview with David Sheff for Playboy magazine, Lennon commented on the message of "Imagine":

Ono indicated that the lyrical content of "Imagine" was "just what John believed—that we are all one country, one world, one people. He wanted to get that idea out." In addition, the content of "Imagine" was inspiration for the concept of Nutopia: The Country of Peace, created in 1973. Lennon included a symbolically mute "anthem" to this country on his album Mind Games. The inspiration for Ono's Imagine Peace Tower in Iceland came from words in the second verse: "Imagine all the people living life in peace."

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.

Connie Talbot (born 20 November 2000) is an English child singer from Streetly, Aldridge. She rose to fame in 2007 when she reached the final of the first series of Britain's Got Talent, where she was runner-up to Paul Potts. Talbot was supposed to sign with Sony BMG but the label pulled out of the deal due to her age.

Talbot signed with Rainbow Recording Company and released her debut album Over the Rainbow in the UK on 26 November 2007. The album was re-released 18 June 2008 with a new track listing, and the first single from the album, a cover of Bob Marley's "Three Little Birds", was released on 10 June.

Despite its negative critical reception, Over the Rainbow has sold over 250,000 copies worldwide and reached number one in three countries. Since the initial album release, Talbot has performed publicly and on television in Europe, the U.S. and across Asia, where her music had gained recognition through YouTube. Her second album, Connie Talbot's Christmas Album, was released on 24 November 2008; her third, Holiday Magic, was released in late 2009. While pursuing her musical career, Talbot attends school, and lives in Streetly with her family.

Herbert Jeffrey "Herbie" Hancock (born April 12, 1940) is an American pianist, keyboardist, bandleader and composer. As part of Miles Davis's Second Great Quintet, Hancock helped to redefine the role of a jazz rhythm section and was one of the primary architects of the "post-bop" sound. He was one of the first jazz musicians to embrace music synthesizers and funk music (characterized by syncopated drum beats). Hancock's music is often melodic and accessible; he has had many songs "cross over" and achieved success among pop audiences. His music embraces elements of funk and soul while adopting freer stylistic elements from jazz. In his jazz improvisation, he possesses a unique creative blend of jazz, blues, and modern classical music, with harmonic stylings much like the styles of Claude Debussy and Maurice Ravel.

Hancock's best-known solo works include "Cantaloupe Island", "Watermelon Man" (later performed by dozens of musicians, including bandleader Mongo Santamaría), "Maiden Voyage", "Chameleon", and the singles "I Thought It Was You" and "Rockit". His 2007 tribute album River: The Joni Letters won the 2008 Grammy Award for Album of the Year, only the second jazz album ever to win the award after Getz/Gilberto in 1965.
