Question: Where was Led Zeppelin's album recorded that included a song written by Anne Bredon?
Context: "Babe I'm Gonna Leave You" is a folk song written by Anne Bredon (then known as Anne Johannsen) in the late 1950s.  It was recorded by Joan Baez (credited and became widely popular as "traditional") and released on her 1962 album "Joan Baez in Concert, Part 1"; and by the English rock band Led Zeppelin, who included it on their 1969 debut album "Led Zeppelin". 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. Great Zeppelin: A Tribute to Led Zeppelin is a cover album released by the American hard rock band Great White in 1998, dedicated to songs of Led Zeppelin.  It was recorded live in a concert that took place at The Galaxy Theatre of Santa Ana, California, USA, in December 1996 and released by the French label Axe Killer.  The American edition was issued by Deadline Records in 1999.  Deadline Records also issued a very rare vinyl version of the album in 1999, omitting 4 tracks due to time limitations of vinyl.  Songs from this album appear on many compilations and also on re-issues of older albums as bonus tracks.  The album was re-issued in 2005 by the Canadian label Legacy, with the title Great White Salutes Led Zeppelin.  The entire album appears also on Great White's double-CD compilation "A Double Dose" issued by Deadline Music in 2005, along with the album of covers "Recover". "Whole Lotta Love" is a song by English hard rock band Led Zeppelin.  It is the opening track on the band's second album, "Led Zeppelin II", and was released in the United States, several countries in Europe, and Japan as a single; as with other Led Zeppelin songs, no single was released in the United Kingdom.  The US release became their first hit single, being certified Gold on 13 April 1970, having sold one million copies.  It reached number one in Germany, and number four in the Netherlands.  Parts of the song were adapted from Willie Dixon's "You Need Love", recorded by Muddy Waters in 1962; originally uncredited to Dixon, a lawsuit in 1985 was settled with a payment to Dixon and credit on subsequent releases. Led Zeppelin is the eponymous debut studio album by English rock band Led Zeppelin, released on 12 January 1969 in the United States and on 31 March 1969 in the United Kingdom by Atlantic Records.  Featuring integral contributions from each of the group's four members, the album was recorded in October 1968 at Olympic Studios in London and established their fusion style of both blues and rock music.  It also attracted a large and devoted following to the band; Zeppelin's take on the emerging hard rock sound endeared them to parts of the counterculture on both sides of the Atlantic Ocean. "Immigrant Song" is a 1970 song by the English rock band Led Zeppelin.  It is built on a repeating riff and features lyrical references to Norse mythology, with singer Robert Plant's howling vocals mentioning war-making and Valhalla .  The song was included on their third studio album, "Led Zeppelin III", and was released as a single, which charted in several countries.  Several live recordings have also been issued on Led Zeppelin concert albums and other artists have recorded renditions of the song. 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. "Taurus" is a rock instrumental by American rock band Spirit, originally released on their self-titled debut album in 1968.  The track, composed by guitarist/singer Randy California, was recorded in November 1967.  It has been alleged that Jimmy Page borrowed the descending guitar figure from "Taurus" for Led Zeppelin's signature song "Stairway to Heaven".  Led Zeppelin opened for Spirit in an early American tour, providing the possibility that Led Zeppelin had heard the Spirit song before "Stairway to Heaven" was written.  In the liner notes to the 1996 reissue of Spirit's debut album, songwriter Randy California writes: "No Quarter" is a song by Led Zeppelin that appears on their 1973 album "Houses of the Holy".  It was written by John Paul Jones, Jimmy Page and Robert Plant.  The song became a centerpiece at all Led Zeppelin concerts thereafter, until their final tour.  It appears in both the film versions and both live album versions of "The Song Remains the Same" released in 1976 and expanded in 2007.  It appeared once more in 1994 on Page and Plant's as the title track.  It also appears on Led Zeppelin's 2012 live album "Celebration Day", which documented their 2007 reunion performance at the O2 Arena in London.  It was re-released in the deluxe edition of "Houses of the Holy". 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.
