Editing Jethro Tull (band) (section)

===''Stand Up'' to ''Aqualung'' (1969–1971)===
After Barre joined, the group played a few shows supporting [[Jimi Hendrix]] in Scandinavia,{{sfn|Rabey|2013|p=49}} then began  an extensive tour of the US supporting [[Led Zeppelin]] and [[Vanilla Fudge]].{{sfn|Rees|1998|p=31}} Jethro Tull attracted a substantial live following, and Ellis and Wright asked Anderson, who had become the principal songwriter, to write a hit single. The result was "[[Living in the Past (song)|Living in the Past]]", which reached No. 3 in May 1969 on the UK singles chart and No. 11 in the US{{sfn|Rees|1998|p=31}} and resulted in an appearance on ''[[Top of the Pops]]''.

The next album was ''[[Stand Up (Jethro Tull album)|Stand Up]]'', recorded during April–May and August 1969.{{sfn|Rabey|2013|p=52}} It was released in September 1969 and quickly reached No. 1 in the UK, the only album by the group to do so. Anderson had now established himself as leader and songwriter and wrote all the material for the album, except for his jazzy rearrangement of [[Johann Sebastian Bach|J. S. Bach]]'s "[[Bourrée in E minor]] BWV 996 (fifth movement)".{{sfn|Rees|1998|p=32}} The cover of the album unfolded to show a photo insert of the band attached like a [[pop-up book]].

Immediately after releasing ''Stand Up'', the group set off on their first headlining tour of the US, which included an appearance at the [[Newport Jazz Festival]].{{sfn|Rees|1998|p=33}} Barre recalled, "It was really the turning point for Jethro Tull—for everything that we were to become and everything we were to inspire in others."<ref>{{Cite web |url=http://www.tullpress.com/gwjun99.htm |title=Guitar World, June, 1999 |access-date=17 May 2014 |archive-url=https://web.archive.org/web/20120311053104/http://www.tullpress.com/gwjun99.htm |archive-date=11 March 2012 |url-status=dead }}</ref> The band was invited to play at the [[Woodstock|Woodstock Festival]] but Anderson declined, not wanting to be associated with the [[hippie]] movement and risk being permanently moulded into one type of sound.<ref>{{Cite web|url=http://www.tullpress.com/craug01.htm|title=Jethro Tull Press: Classic Rock, August 2001|website=Tullpress.com|access-date=15 July 2022}}</ref>

On 29 January 1970, Jethro Tull appeared again on BBC's ''Top of the Pops'', performing "Witch's Promise".<ref>{{cite web |url=http://www.tv.com/shows/top-of-the-pops-uk/29th-january-1970-943665/ |title=Top of the Pops (UK)&nbsp;– Season 7, Episode 5: 29th January 1970 |work=TV.com |access-date=30 January 2016 |archive-date=7 March 2016 |archive-url=https://web.archive.org/web/20160307152715/http://www.tv.com/shows/top-of-the-pops-uk/29th-january-1970-943665/ |url-status=dead }}</ref><ref>{{YouTube|-0GAuexrVzo|Jethro Tull&nbsp;– The Witches Promise}}</ref> Evan rejoined the band in early 1970; he had stayed in London, sharing a flat with Anderson, after the John Evan Band broke up, and was studying music at the [[University of London]]. He was initially reluctant to rejoin the band because of his studies, which gave him access to a free studio,{{sfn|Rabey|2013|p=65}} but he had played as a [[session musician]] on Tull's next album, ''[[Benefit (album)|Benefit]]'' (1970), and when Anderson needed someone to play the keyboard parts on tour, his tutor persuaded him that rejoining would be a good idea.{{sfn|Rees|1998|pp=36–37}} The album reached No. 4 in the UK and No. 11 in the US{{sfn|Rees|1998|p=186}} and the group sold out 20,000-seat arenas, establishing themselves as a premier live act.<ref>{{cite magazine|url=https://www.rollingstone.com/music/artists/jethro-tull/biography |archive-url=https://web.archive.org/web/20110710091246/http://www.rollingstone.com/music/artists/jethro-tull/biography |url-status=dead |archive-date=10 July 2011 |title=Jethro Tull Biography |magazine=Rolling Stone |date=28 June 2013}}</ref> In August they played to one of their largest audiences at the [[Isle of Wight Festival 1970|1970 Isle of Wight festival]].<ref>{{cite web|url=http://www.allmusic.com/album/nothing-is-easy-live-at-the-isle-of-wight-1970-dvd-mw0001016771|title=Nothing Is Easy : Live at the Isle of Wight 1970|first=Bruce|last=Eder|website=AllMusic|access-date=11 August 2014}}</ref>

The Isle of Wight appearance was followed by another US tour, in the course of which Jethro Tull became only the second rock band after [[The Beatles]] to perform at [[Carnegie Hall]] in New York City.{{sfn|Benson|2002|p=28}} Cornick left the band at the end of the tour: he had wanted to socialise on tour, while the other band members were more reclusive.<ref name="cornick"/> Cornick said later that he was fired by Anderson,{{sfn|Rees|1998|p=39}} while the band's official website said he was "invited to leave" and was given encouragement and support to form his own band.<ref name="cornick">{{cite web|url=http://www.j-tull.com/musicians/pastmembers/glenncornick.html|archive-url=https://web.archive.org/web/20110514082429/http://www.j-tull.com/musicians/pastmembers/glenncornick.html|archive-date=14 May 2011|title=Glenn Cornick|publisher=Jethro Tull (official website)|access-date=14 May 2011}}</ref> Cornick subsequently formed Wild Turkey, a band which he revived for Jethro Tull fan conventions decades later.

Anderson invited [[Jeffrey Hammond]] to replace Cornick, buying him a new bass for the purpose.{{sfn|Rabey|2013|p=73}} Hammond had not played an instrument since leaving the John Evan Band, and he was chosen more for his compatibility with the other band members than for his musical skills.{{sfn|Rees|1998|p=39}} This line-up recorded ''[[Aqualung (album)|Aqualung]]'' in late 1970 (released in 1971). The album was split into two parts, subtitled "Aqualung" and "My God", and featured among other things Anderson's views on organised religion.{{sfn|Rabey|2013|p=76}} Recording the album was problematic because of technical difficulties in the studio, and also because of Hammond's rusty musical skills. On "[[Locomotive Breath]]", Anderson recorded the backing track by himself, singing to a [[Hi-hat (instrument)|hi-hat]] accompaniment, and the rest of the band added their parts later.{{sfn|Rabey|2013|p=77}} Despite Anderson's concern that it may have been "too radical" compared with the band's previous albums, ''Aqualung'' was the first Jethro Tull album to reach the top ten in the US, peaking at No. 7.{{sfn|Rees|1998|p=186}} It sold over one million copies, earning it a [[Music recording sales certification|gold disc]] by the [[Recording Industry Association of America|RIAA]] in July 1971.{{sfn|Murrells|1978|p=295}}
