Question: What song from the Beatles ninth studio album was written by George Harrison?

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: The Beatles discography: In their native United Kingdom, during 1962–1970, the Beatles released 12 studio albums, 13 extended plays (EPs) and 22 singles. However, the band's international discography is complicated, due to different versions of their albums sometimes being released in other countries, particularly during their early years on Capitol Records in North America. The Beatles' discography was originally released on the vinyl format, with full-length long plays (LPs), shorter EPs and singles. Over the years, the collection has also been released on cassette, 8-track, compact disc (CD), and on a USB flash drive in MP3 and 24-bit FLAC format. Although their output has come to include vault items and remixed mash-ups, the Beatles' "core catalogue", recorded in 1962–1970, is 217 songs totalling approximately 10 hours of music. Additionally, they released five tracks that are different versions of previously released songs: "Love Me Do", "Revolution", "Get Back", "Across the Universe" and "Let It Be"; two tracks in German: "Komm, Gib Mir Deine Hand" and "Sie Liebt Dich"; and two tracks that are duplicates of songs included on previous albums but also included on the album "Yellow Submarine": "Yellow Submarine" and "All You Need Is Love".
Document 3: Pepperland (song): "Pepperland" is an instrumental orchestral piece conducted and composed by The Beatles' producer George Martin for the "Yellow Submarine" film and was the introduction to the orchestral Side 2 of the film's soundtrack album by The Beatles, released in 1969. The song was recorded by a 41-piece orchestra at Abbey Road Studios on 22–23 October 1968. The piece, as with the others in the film, is tailored to the vibrant visuals of the film, so contain novelty sounds, effects, and musical experimentation that are better understood when paired with these visuals for some, however these pieces of music can also be admired for their beauty on their own.
Document 4: Pepperland Laid Waste: "Pepperland Laid Waste" is an instrumental orchestral piece conducted and composed by The Beatles' producer George Martin for the "Yellow Submarine" film and was the sixth track on the orchestral Side 2 of the film's soundtrack album by The Beatles, released in 1969.
Document 5: 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 6: A Hard Day's Night (album): A Hard Day's Night is the third studio album by the English rock band the Beatles, released on 10 July 1964, with side one containing songs from the soundtrack to their film "A Hard Day's Night". The American version of the album was released two weeks earlier, on 26 June 1964 by United Artists Records, with a different track listing. In contrast to their first two albums, all 13 tracks on "A Hard Day's Night" were written by John Lennon and Paul McCartney showcasing the development of their songwriting talents. The album includes the title track, with its distinct opening chord, and the previously released "Can't Buy Me Love", both transatlantic number-one singles for the band.
Document 7: The Yellow Album: The Yellow Album is "The Simpsons" second album of originally recorded songs, released as a follow-up to the 1990 album "The Simpsons Sing the Blues". Though it was released in 1998, it had been recorded years earlier, after the success of the first album. The title is a play on the name of The Beatles' highly popular self-titled 1968 album, commonly known as ""The White Album"", with the skin color of the characters of "The Simpsons". In addition, the cover is a parody of The Beatles' 1967 album, "Sgt. Pepper's Lonely Hearts Club Band".
Document 8: 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 9: 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").

Released on 26 May 1967 in the United Kingdom and 2 June 1967 in the United States, it was an immediate commercial and critical success, spending 27 weeks at the top of the UK albums chart and 15 weeks at number one in the US. On release, the album was lauded by the vast majority of critics for its innovations in music production, songwriting and graphic design, for bridging a cultural divide between popular music and legitimate art, and for providing a musical representation of its generation and the contemporary counterculture. It won four Grammy Awards in 1968, including Album of the Year, the first rock LP to receive this honour.
Document 11: Abbey Road: Abbey Road is the eleventh studio album by English rock band the Beatles, released on 26 September 1969 by Apple Records. The recording sessions for the album were the last in which all four Beatles participated. Although "Let It Be" was the final album that the Beatles completed before the band's dissolution in April 1970, most of the album had been recorded before the "Abbey Road" sessions began. A double A-side single from the album, "Something"/"Come Together", released in October, topped the "Billboard" chart in the US.
Document 12: Piggies: "Piggies" is a song by the English rock group the Beatles from their 1968 album "The Beatles" (also known as "the White Album"). Written by George Harrison as a social commentary, the song serves as an Orwellian satire on greed and consumerism. Among several elements it incorporates from classical music, the track features harpsichord and orchestral strings in the baroque pop style, which are contrasted by Harrison's acerbic lyrics and the sound of grunting pigs. Although credited to George Martin, the recording was largely produced by Chris Thomas, who also contributed the harpsichord part.
Document 13: March of the Meanies: "March of the Meanies" is an instrumental orchestral piece conducted and composed by The Beatles' producer George Martin for the "Yellow Submarine" film and was the fifth track on the orchestral Side 2 of the film's soundtrack album by The Beatles, released in 1969.

Document 15: Helter Skelter (song): "Helter Skelter" is a song by the English rock band the Beatles that was released in 1968 on their self-titled double album, often known as "the White Album". It was written by Paul McCartney and credited to Lennon–McCartney. The song was a product of McCartney's attempt to create a sound as loud and dirty as possible. The Beatles' recording has been noted for its "proto-metal roar" and is considered by music historians to be a key influence in the early development of heavy metal. "Rolling Stone" magazine ranked "Helter Skelter" 52nd on its list of the "100 Greatest Beatles songs".
