Context paragraphs:
Deborah Bonham: Deborah Bonham (born 7 February 1962) is an English rock and blues vocalist and the sister of John Bonham, the late drummer for the band Led Zeppelin.  Born in Redditch, Worcestershire, England, she lived with her father in The Old Hyde farm, Cutnall Green, Worcestershire (the location where John Bonham's fantasy sequence was filmed for "The Song Remains the Same").  While living there, she started playing and recording music with her nephew Jason Bonham who has played drums on her two most recent studio releases.

Bonzo's Montreux: "Bonzo's Montreux" is a drum solo by Led Zeppelin drummer John Bonham.  It is the seventh track on the band's final studio album, "Coda".  It was recorded in September 1976 at Mountain Studios in Montreux, Switzerland.  Jimmy Page added electronic effects afterwards.

Led Zeppelin discography: 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.

Jason Bonham: Jason John Bonham (born 15 July 1966) is an English drummer.  Bonham is perhaps best known for being the son of the late Led Zeppelin drummer John Bonham and Patricia "Pat" Bonham (born Phillips).  After his father's death in September 1980, he played with Led Zeppelin on different occasions, including the Ahmet Ertegun Tribute Concert at The O2 Arena in London in 2007.

Tea for One: "Tea for One" is the last track on Led Zeppelin's 1976 album "Presence".  It begins with mid-tempo interplay between guitarist Jimmy Page and drummer John Bonham before settling into a sotto voce groove.  The song evolves into a slow blues epic, featuring lyrics which deal with homesickness and loneliness.  Much of this was felt by Robert Plant, who recalls sitting alone in a New York hotel during a U.S. concert tour drinking "tea for one".  Other members of the band, notably John Bonham, were also widely reported to suffer from homesickness during Led Zeppelin's concert tours.

Jimmy Page: James Patrick Page, {'1': ", '2': ", '3': ", '4': "} (born 9 January 1944) is an English musician, songwriter, and record producer who achieved international success as the guitarist and founder of the rock band Led Zeppelin.

Coda (album): Coda is the ninth and final studio album by the English rock band Led Zeppelin, released in 1982.  The album is a collection of unused tracks from various sessions during Led Zeppelin's twelve-year career.  It was released two years after the group had officially disbanded following the death of drummer John Bonham.  The word "coda", meaning a passage that ends a musical piece following the main body, was therefore chosen as the title.

Bonham (band): Bonham was a British band founded in 1989 by drummer Jason Bonham, the son of the late Led Zeppelin drummer John Bonham.  The band's most successful line-up included singer Daniel MacMaster, bassist/keyboardist John Smithson and guitarist Ian Hatton.

The band cancelled the tour when drummer John Bonham died on 25 September, one day after the group's initial rehearsal for the tour.

Ahmet Ertegun Tribute Concert: The Ahmet Ertegun Tribute Concert was a benefit concert held in memory of music executive Ahmet Ertegün at the O2 Arena in London on December 10, 2007.  The headline act was the English rock band Led Zeppelin, who performed their first full-length concert since the death of drummer John Bonham in 1980, in a one-off reunion.
