The U.S. vs. John Lennon

Imagine: John Lennon is a 1988 documentary film about English musician John Lennon.
Reimagining is an album by American jazz pianist Vijay Iyer, which was recorded in 2004, originally released on the Savoy label and reissued in Europe by Pi Recordings.
 The follow-up to "Blood Sutra", the record features nine Iyer's compositions for his quartet with Rudresh Mahanthappa on alto sax, Stephan Crump on bass and Marcus Gilmore on drums, and a solo piano interpretation of John Lennon's "Imagine".
Walls and Bridges is the fifth studio album by English musician John Lennon.
 It was issued by Apple Records on 26 September 1974 in the United States and on 4 October in the United Kingdom.
 Written, recorded and released during his 18-month separation from Yoko Ono, the album captured Lennon in the midst of his "Lost Weekend".
 "Walls and Bridges" was an American "Billboard" number-one album and featured two hit singles, "Whatever Gets You thru the Night" and "#9 Dream".
 The first of these was Lennon's first number-one hit in the United States as a solo artist, and his only chart-topping single in either the US or Britain during his lifetime.
Cynthia Lennon (née Powell; 10 September 1939 – 1 April 2015) was the first wife of English musician John Lennon and mother of Julian Lennon.
 She grew up in the middle-class section of Hoylake, on the Wirral Peninsula in North West England.
 At the age of 12, she was accepted into the Junior Art School, and was later enrolled in the Liverpool College of Art.
 John Lennon also attended the college; a meeting with Powell in a calligraphy class led to their relationship.
"I Found Out" is a song by the English musician John Lennon from his 1970 album "John Lennon/Plastic Ono Band".
"Well Well Well" is a song by English musician John Lennon from his 1970 album "John Lennon/Plastic Ono Band".
 The eighth and longest track on the album, "Well Well Well" features a blistering guitar part, screaming vocals and a brutal, pounding backing track.
"Mother" is a song by English musician John Lennon, first released on his 1970 album "John Lennon/Plastic Ono Band".
 An edited version of the song was issued as a single in the United States on Apple Records, on 28 December 1970.
 The single runs about 1:41 shorter than the album due to a lack of the tolling bells intro and a quicker fadeout.
 The B-side features "Why" by Yoko Ono.
 The song peaked in the US at number 19 on the "Cashbox" Top 100 and number 43 on the "Billboard" Hot 100.
"I'm the Greatest" is a song written by English musician John Lennon that was released as the opening track of the 1973 album "Ringo" by Ringo Starr.
 With Starr, Lennon and George Harrison appearing on the track, it marks the only time that three former Beatles recorded together between the band's break-up in 1970 and Lennon's death in 1980.
 Lennon wrote the song in December 1970 as a wry comment on his rise to fame, and later tailored the composition for Starr to sing.
 Named after one of Muhammad Ali's catchphrases, the song partly evokes the stage-show concept of the Beatles' 1967 album "Sgt. Pepper's Lonely Hearts Club Band".
"Imagine" is a song written and performed by English musician John Lennon.
 The best-selling single of his solo career, its lyrics encourage the listener to imagine a world at peace without the barriers of borders or the divisions of religion and nationality, and to consider the possibility that the whole of humanity would live unattached to material possessions.
The U.S. vs. John Lennon is a 2006 documentary film about English musician John Lennon's transformation from a member of The Beatles to a rallying anti-war activist striving for world peace during the late 1960s and early 1970s.

 The film had its world premiere at the Venice Film Festival and its North American premiere at the Toronto International Film Festival.
 It was released in New York City and Los Angeles, California on 15 September 2006, and had a nationwide release on 29 September.
 A soundtrack composed of John Lennon tracks was released by Capitol Records and EMI on 26 September 2006.
