Context: Chapter 27 is a 2007 biographical film depicting the murder of John Lennon by Mark David Chapman.  It was written and directed by Jarrett Schaefer, based on the book "Let Me Take You Down" by Jack Jones, produced by Robert Salerno, and stars Jared Leto as Chapman.  The film takes place in December 1980, and is intended to be an exploration of Chapman's psyche. Anna-Lou "Annie" Leibovitz ( ; born October 2, 1949) is an American portrait photographer.  She photographed John Lennon on the day he was assassinated, and her work has been used on numerous album covers and magazines.  She is the first woman to have held an exhibition at Washington's National Portrait Gallery in 1991. Lennon Legend: The Very Best of John Lennon is the third official compilation album of John Lennon's solo career, coming after 1975's "Shaved Fish" and 1982's "The John Lennon Collection".  Because neither collection spanned Lennon's releases up to and including 1984's "Milk and Honey", "Lennon Legend: The Very Best of John Lennon" – considered the definitive Lennon retrospective – was compiled to rectify the situation.  It was released in the UK in 1997 through Parlophone and early 1998 in the US by EMI Records. All Things Must Pass is a triple album by English musician George Harrison.  Recorded and released in 1970, the album was Harrison's first solo work since the break-up of the Beatles in April that year, and his third solo album overall.  It includes the hit singles "My Sweet Lord" and "What Is Life", as well as songs such as "Isn't It a Pity" and the title track that had been turned down for inclusion on releases by the Beatles.  The album reflects the influence of Harrison's musical activities with artists such as Bob Dylan, the Band, Delaney & Bonnie and Billy Preston during 1968–70, and his growth as an artist beyond his supporting role to former bandmates John Lennon and Paul McCartney.  "All Things Must Pass" introduced Harrison's signature sound, the slide guitar, and the spiritual themes that would be present throughout his subsequent solo work.  The original vinyl release consisted of two LPs of songs and a third disc of informal jams, titled "Apple Jam".  Several commentators interpret Barry Feinstein's album cover photo, showing Harrison surrounded by four garden gnomes, as a statement on his independence from the Beatles.

"Evening Wear/Mark David Chapman" peaked at number 2 on the "Billboard" Hot 100 Singles Sales chart and number 1 on the Hot Dance Singles Sales chart.
