Isolation (John Lennon song): "Isolation" is a 1970 song appearing on John Lennon's first official solo album release, "John Lennon/Plastic Ono Band".  It ends side one of the album, and is the fifth track.  In the Philippines Apple Records released "Isolation" as the b-side to "Mother", the single off "John Lennon/Plastic Ono Band", in contrast to most countries where the b-side was Yoko Ono's "Why."  It was also released on an EP in Mexico along with "Mother," "Look at Me'" and "My Mummy's Dead."

My Mummy's Dead: "My Mummy's Dead" is the closing song on the album "John Lennon/Plastic Ono Band" by John Lennon.  It was also released on a Mexican EP that also contained "Mother", "Isolation" and "Look at Me."

John Lennon/Plastic Ono Band: 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.

Yoko Ono/Plastic Ono Band: 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.

Sweet Toronto: 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."

Mother (John Lennon song): "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.

Hold On (John Lennon song): "Hold On" is a song from the album "John Lennon/Plastic Ono Band" by John Lennon.
