John and Yoko: A Love Story is a 1985 television drama that chronicles the lives of John Lennon and Yoko Ono, beginning just before they met in 1966 and concluding with Lennon's murder in 1980.  The movie was made with the co-operation of Yoko Ono, who controlled the song rights. John Lennon Museum (ジョン・レノン・ミュージアム , Jon Renon Myūjiamu ) was a museum located inside the Saitama Super Arena in Chūō-ku, Saitama, Saitama Prefecture, Japan.  It was established to preserve knowledge of John Lennon's life and musical career.  It displayed Lennon's widow Yoko Ono's collection of his memorabilia as well as other displays.  The museum opened on October 9, 2000, the 60th anniversary of Lennon’s birth, and closed on September 30, 2010, when its exhibit contract with Yoko Ono expired.  A tour of the museum began with a welcoming message and short film narrated by Yoko Ono (in Japanese with English headphones available), and ended at an avant-garde styled "reflection room" full of chairs facing a slide show of moving words and images.  After this room there was a gift shop with John Lennon memorabilia available. Sweet Toronto (sometimes referred as Sweet Toronto Peace Festival) is a documentary by D.A. Pennebaker of the Toronto Rock and Roll Revival, a one-day festival held September 13, 1969 at Varsity Stadium on the campus of the University of Toronto and attended by some 20,000 persons.  The event was produced by John Brower and Ken Walker.  John Lennon played as part of the Plastic Ono Band, whose members also included Yoko Ono, Klaus Voorman, Alan White, and Eric Clapton.  (Their set was released as the album "Live Peace in Toronto 1969".)  The video also features a selection of other acts: Jerry Lee Lewis, Little Richard, and Bo Diddley.  The actual concert lasted twelve hours, but Pennebaker's documentary focuses mainly on the final hours of the concert.  At the time of the performance Yoko Ono's popularity was sufficiently low that the audience booed and left the Plastic Ono Band performance.  There was a similar response from film reviewers at the time.  The performances "and this film have grown in interest and watchability since that time, particularly given the rarity of such thorough documentation of these key performers' work in concert." Don't Stop Me!  EP is an iTunes exclusive EP release by Yoko Ono as Yoko Ono Plastic Ono Band.  The album is also available in the form of a promotional-only compact disc, leading up to her album "Between My Head and the Sky", released in September 2009.  It features a remix of "The Sun Is Down!"  by Japanese musician Cornelius, who also features in the new Plastic Ono Band lineup on "Between My Head and the Sky". John Lennon/Plastic Ono Band is the debut studio album by English rock musician John Lennon.  It was released in 1970, after Lennon had issued three experimental albums with Yoko Ono and "Live Peace in Toronto 1969", a live performance in Toronto credited to the Plastic Ono Band.  The album was recorded simultaneously with Ono's debut avant garde solo album, "Yoko Ono/Plastic Ono Band", at Ascot Sound Studios and Abbey Road Studios using the same musicians and production team and nearly identical cover artwork. Sean Taro Ono Lennon (Japanese: 小野 太郎 , Hepburn: Ono Tarō , born October 9, 1975) is an American singer, songwriter and actor.  He is the son of John Lennon and Yoko Ono. Onobox is a 1992 comprehensive 6-disc collection of Yoko Ono's work from 1968 to 1985.  The discs are grouped by era and theme.  Disc three features the entire "Feeling the Space" project, which was originally conceived and recorded as a double album before being edited down, while disc six is the previously unreleased 1974 album "A Story", which was later reissued separately with an altered track listing, along with the rest of Ono's back catalogue.  There was also an accompanying concise one-disc "greatest hits" release, entitled "Walking on Thin Ice".  While the Rykodisc press release for Onobox declared the collection "not as bad as you might think", it also urged the public to "smash your preconceptions".  Which, for the most part, they did, finding the box gave "Yoko Ono the avant- garde heroine her due". Between My Head and the Sky is an album by Yoko Ono released on Chimera Music in September 2009.  This is her first studio album to be released as "Yoko Ono/Plastic Ono Band" since 1973's "Feeling the Space".  The new Plastic Ono Band lineup features Cornelius, Yuka Honda (of Cibo Matto fame) and Ono's son Sean Lennon as band leader and producer. Yoko Ono/Plastic Ono Band is the avant-garde debut studio album by Yoko Ono.  The album came after recording three experimental releases with John Lennon and a live album as a member of The Plastic Ono Band.
