the first verse accompanied by the backing guitar chords: Bassist John Paul Jones complements Page on mandolin. The second verse contains the chorus, at the beginning of which Jones on bass and drummer John Bonham come in – Jones follows the chord changes and Bonham plays a straightforward, backing beat. Through the use of double tracking, Plant provides a harmony vocal line. Page also adds pedal steel guitar fills; however, he departs from the typical American country music approach by adding a wah-wah pedal tonal effect. For the third verse, Plant returns to singing accompanied by guitar chording. The verses are broken up with an instrumental middle section with Page, Jones, and Bonham. Page solos on a heavily sustained Gibson Les Paul Standard electric guitar, which is also double tracked. Led Zeppelin biographer Dave Lewis calls it "a smooth woman-tone solo" After a second chorus, the song winds down with pedal steel fills and ends with an acoustic guitar figure. Led Zeppelin recorded the song at Headley Grange, Headley, East Hampshire, using the Rolling Stones Mobile Studio. The song was engineered and later mixed by Andy Johns at Olympic Studios in London. Disagreement over lyrics Although writers do not question who composed the music for the song, there is some disagreement over who wrote the lyrics. In addition to being credited as the songwriter on all Led Zeppelin releases, Page claims to be responsible for the lyrics: "I'd written it after an old emotional upheaval and I just changed a few of the lyrics for the new version". "Tangerine" and "Dazed and Confused" are the only Led Zeppelin songs with lyrics that credit Page as the sole songwriter. However, Case, Shadwick, and Williamson identify the Yardbirds' song as a joint or co-composition by Page and Yardbirds' singer and primary lyricist Keith Relf. Yardbirds' drummer Jim McCarty and bassist Chris Dreja both assert that Relf wrote the words for "Knowing That I'm Losing You"; they and Jane Relf (sister and singer who also performed with Relf) believe some of his original lines found their way into "Tangerine". Release and influence "Tangerine" was issued as an album track on Led Zeppelin III on 5 October 1970 in the US and 23 October 1970 in the UK and quickly went to number one on the album charts. It was included on the LP record's second side, which featured more acoustic- and folk-influenced tunes.
