Question: Who wrote "All My Love" and was bassist for English rock band, Led Zeppelin?
Context: Physical Graffiti is the sixth studio album by the English rock band Led Zeppelin, released as a double album on 24 February 1975 by their newly founded imprint label Swan Song Records.  The band wrote and recorded eight new songs for the album at Headley Grange, which stretched the total time of the record beyond the typical length of a single LP, so the band decided to make "Physical Graffiti" a double album by including unreleased tracks from earlier recording sessions: one outtake from "Led Zeppelin III," three from "Led Zeppelin IV," and three from "Houses of the Holy", including the unused title track from the latter album. The discography of the English rock band Led Zeppelin consists of nine studio albums, four live albums, nine compilation albums, 16 singles and eight music downloads. Formed in London in 1968, the group consisted of guitarist Jimmy Page, singer Robert Plant, bass player John Paul Jones, and drummer John Bonham.  The band pioneered the concept of album-oriented rock and often refused to release popular songs as singles.  Nevertheless, four of their ten songs that reached the Hot 100 had no mention of the title in the lyrics: "Immigrant Song", "Black Dog", "Over the Hills and Far Away", "D'yer Mak'er".  Their debut album, "Led Zeppelin" (1969), released by Atlantic Records, charted at number six on the UK Albums Chart and at number ten on the United States "Billboard" 200.  It received several sales certifications, including an 8 times multi-platinum from the Recording Industry Association of America (RIAA) and Diamond from the Music Canada.  Led Zeppelin's second studio album, "Led Zeppelin II", recorded when the band were on tour, was released a few months after the first.  It reached number one in several countries, including the UK and the US, where it was certified 12 times multi-platinum.  The album produced Led Zeppelin's most successful single, "Whole Lotta Love", which peaked at several music charts in the top 10. " Led Zeppelin III" (1970) was a softer, more folk-based effort compared to the hard rock of the band's previous releases.  It also peaked at number one in the UK and in the US. Led Zeppelin II is the eponymous second studio album by the English rock band Led Zeppelin, released on 22 October 1969 in the United States and on 31 October 1969 in the United Kingdom by Atlantic Records.  Recording sessions for the album took place at several locations in both the United Kingdom and North America from January to August 1969.  The album's production was credited to the band's lead guitarist and songwriter Jimmy Page, and it also served as Led Zeppelin's first album to utilise the recording techniques of the engineer Eddie Kramer.  Incorporating several elements of blues and folk music, "Led Zeppelin II" exhibited the band's evolving musical style of blues-derived material and their guitar riff-based sound.  It has been described as the band's heaviest album. Led Zeppelin Boxed Set 2 is a double album released by Atlantic Records on 21 September 1993.  This box set features the rest of the English rock band Led Zeppelin's catalogue not included in the 1990 4-CD box set "Led Zeppelin", all digitally remastered, including the previously unreleased studio track "Baby Come On Home".  A 54-page booklet was also included with the release.  Between this box set and the 4-CD box set every track from the band's nine studio albums are featured along with two BBC live recordings; the band's only non-LP b-side; and one studio outtake. Led Zeppelin Remasters is a three-LP (or two-cassette or two-CD) compilation album of digitally remastered material by English rock band Led Zeppelin.  Containing songs from eight of the band's nine studio albums, it was initially released in the UK and Japan by Atlantic Records on 15 October 1990.  The album is essentially a scaled-down version of the four-CD "Led Zeppelin Boxed Set". No Quarter is a live album by Jimmy Page & Robert Plant, both formerly of English rock band Led Zeppelin.  It was released by Atlantic Records on 14 October 1994.  The long-awaited reunion between Jimmy Page and Robert Plant occurred on a 90-minute "UnLedded" MTV project, recorded in Morocco, Wales, and London.  It was not a reunion of Led Zeppelin, however, as former bassist and keyboardist John Paul Jones was not present.  In fact, Jones was not even told about the reunion by his former bandmates.  He later commented that he was unhappy about Plant and Page naming the album after "No Quarter", a Led Zeppelin song which was largely his work. "All My Love" is the sixth track on Led Zeppelin's 1979 album "In Through the Out Door".  Credited to Robert Plant and John Paul Jones, it is a rock ballad that features a synthesizer solo by Jones.  It was written in honour of Plant's son Karac, who died while Led Zeppelin was on their 1977 North American tour. John Richard Baldwin (born 3 January 1946), better known by his stage name John Paul Jones, is an English multi-instrumentalist, songwriter, composer, arranger and record producer.  Best known as the bassist for the English rock band Led Zeppelin, Jones has since developed a solo career.  A versatile musician, Jones also plays organ, guitar, koto, lap steel guitars, mandolin, autoharp, violin, ukulele, sitar, cello, continuum and recorder. The Led Zeppelin bootleg recordings are a collection of audio and video recordings of musical performances by the English rock band Led Zeppelin which were never officially released by the band, or under other legal authority.  The recordings consist of both live concert performances and outtakes from studio sessions conducted by the band.  Many hundreds of Led Zeppelin bootlegs exist, and are widely collected by fans. "Living Loving Maid (She's Just a Woman)" is a song by the English rock band Led Zeppelin from their album "Led Zeppelin II", released in 1969.  It was also released as the b-side of the single "Whole Lotta Love".  The song is about a groupie who stalked the band early in their career.  A misprint by Atlantic Records resulted in the original UK pressings of "Led Zeppelin II" being titled "Livin' Lovin' Wreck (She's a Woman)", with the "Wreck" corrected to "Maid" and the subtitle changed on the US and later releases.
