Question: John Lennon was apart of which band that wrote "Rain"?

full_context: Document 1: Within You Without You: "Within You Without You" is a song written by George Harrison and released on the Beatles' 1967 album "Sgt. Pepper's Lonely Hearts Club Band". It was Harrison's second composition in the Indian classical style, after "Love You To", and was inspired by his six-week stay in India with his mentor and sitar teacher, Ravi Shankar, over September–October 1966. Recorded in London without the other Beatles, the song features Indian instrumentation such as sitar, dilruba and tabla, and was performed by Harrison and members of the Asian Music Circle. The recording marked a significant departure from the Beatles' previous work; musically, it evokes the Indian devotional tradition, while the overtly spiritual quality of the lyrics reflects Harrison's absorption in Hindu philosophy and the teachings of the Vedas. Although the song was his only composition on "Sgt. Pepper", Harrison's endorsement of Indian culture was further reflected in the inclusion of yogis such as Paramahansa Yogananda among the crowd depicted on the album cover.
Document 2: Tomorrow Never Knows: "Tomorrow Never Knows" is a song by the English rock band the Beatles, released as the final track on their August 1966 album "Revolver". Credited as a Lennon–McCartney song, it was written primarily by John Lennon. The song has a vocal filtered through a Leslie speaker cabinet (which was normally used as a loudspeaker for a Hammond organ). Tape loops prepared by the Beatles were mixed in and out of the Indian-inspired modal backing underpinned by a constant but non-standard drum pattern. It marked the first recorded use of reversed sounds in a pop song. "Rain", which was released showcasing the technique three months earlier, was recorded after.
Document 3: Buckets of Rain: "Buckets of Rain" is a song written by Bob Dylan, released in 1975 on his critically acclaimed album "Blood on the Tracks".
Document 4: A Beginning: "A Beginning" is an instrumental piece composed by the Beatles' producer George Martin and intended as an introduction to "Don't Pass Me By", Ringo Starr's first solo composition from the Beatles' 1968 double album "The Beatles" (also known as the "White Album").
Document 5: Revolution (Beatles song): "Revolution" is a song by the Beatles, written by John Lennon and credited to Lennon–McCartney. Three versions of the song were recorded in 1968: a slow, bluesy arrangement (titled "Revolution 1") for the Beatles' self-titled double album, commonly known as "the White Album"; a more abstract musical collage (titled "Revolution 9") that originated as the latter part of "Revolution 1" and appears on the same album; and a faster, hard rock version similar to "Revolution 1", released as the B-side of the "Hey Jude" single. Although the single version was issued first, it was recorded several weeks after "Revolution 1", as a re-make specifically intended for release as a single.
Document 6: A Day in the Life: "A Day in the Life" is a song by the English rock band the Beatles that was released as the final track of their 1967 album "Sgt. Pepper's Lonely Hearts Club Band". Credited to Lennon–McCartney, the verses were written mainly by John Lennon, with Paul McCartney primarily contributing the song's middle section. Lennon's lyrics were inspired by contemporary newspaper articles, including a report on the death of Guinness heir Tara Browne. The recording includes two passages of orchestral glissandos that were partly improvised in the avant-garde style. As with the sustained piano chord that closes the song, the orchestral passages were added after the Beatles had recorded the main rhythm track.
Document 7: The Beatles (album): The Beatles, also known as the White Album, is the ninth studio album by English rock group the Beatles, released on 22 November 1968. A double album, its plain white sleeve has no graphics or text other than the band's name embossed, which was intended as a direct contrast to the vivid cover artwork of the band's earlier "Sgt. Pepper's Lonely Hearts Club Band". Although no singles were issued from "The Beatles" in Britain and the United States, the songs "Hey Jude" and "Revolution" originated from the same recording sessions and were issued on a single in August 1968. The album's songs range in style from British blues and ska to tracks influenced by Chuck Berry and by Karlheinz Stockhausen.
Document 8: No Reply (song): "No Reply" is a song by the English rock band the Beatles from their 1964 album "Beatles for Sale". In North America, it was issued on Capitol Records' variant on the British release, "Beatles '65". The song was written mainly by John Lennon and credited to Lennon–McCartney. Lennon originally gave the song to another artist managed by Brian Epstein, Tommy Quickly, in June 1964, but Quickly decided not to use it. The Beatles recorded the track in London soon after returning from their first full tour of the United States. The lyrics typify Lennon's more introspective and mature songwriting on the "Beatles for Sale" album.
Document 9: Electronic Sound: Electronic Sound is the second studio album by English rock musician George Harrison. Released in May 1969, it was the last of two LPs issued on the Beatles' short-lived Zapple record label, a subsidiary of Apple Records that specialised in the avant-garde. The album is an experimental work comprising two lengthy pieces performed on a Moog synthesizer. Harrison subsequently introduced the instrument to the Beatles' sound, and the band featured synthesizer for the first time on their 1969 album "Abbey Road".
Document 10: Lucy in the Sky with Diamonds: "Lucy in the Sky with Diamonds" is a song credited to Lennon–McCartney that appears on the Beatles' 1967 album "Sgt. Pepper's Lonely Hearts Club Band". It was started by John Lennon, then Paul McCartney contributed to it in a songwriting session. Lennon's son Julian inspired the song with a nursery school drawing he called "Lucy—in the sky with diamonds". Shortly after the song's release, speculation arose that the first letter of each of the title nouns intentionally spelled "LSD". Lennon consistently denied this, insisting the song's fantastical imagery was inspired by Lewis Carroll's "Alice in Wonderland" books, a claim repeatedly confirmed by Paul McCartney.
Document 11: Rain (Uriah Heep song): "Rain" is a song by the English progressive rock/hard rock band Uriah Heep, which was originally released on their fifth studio album, "The Magician's Birthday", in 1972. Though the song was never released as a single, it is one of the most well-known songs from the album. It was written by Ken Hensley, who also performed the keyboard/piano element of the song, with vocals by David Byron. It was the band's first song to utilize only the keyboards/piano and vocals with some additional bass guitar parts. AllMusic said the song was a "lovely piano ballad".
Document 12: Something (Beatles song): "Something" is a song by the Beatles, written by George Harrison and released on the band's 1969 album "Abbey Road". It was also issued as a single coupled with another track from the album, "Come Together". "Something" was the first Harrison composition to appear as a Beatles A-side, and the only song written by him to top the US charts before the band's break-up in April 1970. The single was also one of the first Beatles singles to contain tracks already available on an LP album.
Document 13: Geoff Emerick: Geoffrey Emerick (born 1946) is an English recording studio audio engineer. He worked with The Beatles on their albums "Revolver", "Sgt. Pepper's Lonely Hearts Club Band", "The Beatles" and "Abbey Road".
Document 14: Rain (Beatles song): "Rain" is a song by the English rock band the Beatles first released in May 1966 as the B-side of the "Paperback Writer" single. Both songs were recorded during the sessions for the album "Revolver" although neither appears on that album.
Document 15: Rain in England: Rain in England is an album by American rapper Lil B, released on the label Weird Forest on September 21, 2010. Produced by Lil B under his persona "The Based God", "Rain in England" is unusual for the hip hop genre because it has no percussive beats. Instead, Lil B raps over new-age-style synthesizer music. The lyrical style, which finds Lil B speaking on topics like family, love and death, has been noted for its sincerity and reflectiveness.
