Problem: Background: The Wildhearts are an English rock group, formed in 1989 in Newcastle upon Tyne. The band's sound is a mixture of hard rock and melodic pop music, often described in the music press as combining influences as diverse as The Beatles and 1980s-era Metallica. However, this characterization is denied by the band, who see their influences as being far broader, as shown in the song "29 X The Pain", which lists many of group leader Ginger's influences. Despite several top 20 singles and one top 10 album in Britain, the Wildhearts have not achieved major commercial success, owing in part to difficulties with record companies and many internal problems often relating to recreational drugs and depression.
Context: In early 2001 Ginger announced that he was reforming the Earth vs the Wildhearts lineup of the band for a tour later that year. This lineup (consisting of Ginger and CJ on guitars and vocals, Danny McCormack on bass and vocals, and Stidi on drums) soon ran into difficulty due to McCormack's battle against heroin addiction, and on several dates of the comeback tour Toshi (from support band AntiProduct) stood in as bassist. By 2002 McCormack was once again clean and the band started recording a new mini-album and also toured the UK. The tracks intended for the album were released in the UK in late 2002 across three formats of the "Vanilla Radio" single, and as the mini-album Riff After Riff After Motherfucking Riff in Japan. "Vanilla Radio" reached the top 30 in the UK singles chart, and in early 2003 work began on a full-length album. However, during recording, McCormack checked himself into a rehabilitation center to deal with an alcohol problem, leaving Ginger to play the bass parts on the songs that were newly recorded for the album. McCormack's place in the live band was filled by "Random" Jon Poole, who had already worked with Ginger on his Silver Ginger 5 side project.  The album The Wildhearts Must Be Destroyed, released in 2003, had a very commercial sound, full of short simple pop songs with little of the heavier rock style which often featured on previous albums. The band also managed to get a US record deal with Gearhead Records, which released Riff After Riff in 2004, a compilation of songs from the UK post-reformation singles (all of the songs from this release are also found on the Gut Records compilation Coupled With). Riff After Riff was the Wildhearts' first US release since Earth vs the Wildhearts in 1994. The release was also promoted by a tour, mostly as the support band for their ex-support band, The Darkness.  Then in early 2005, Ginger dissolved the Wildhearts again, citing a mixture of his own personal problems and a lack of commitment within the band. He briefly joined the Brides of Destruction before setting out on his own as a full-time solo artist. In typically unpredictable Wildhearts style, Ginger then reformed the Wildhearts once again for a one-off gig at Scarborough Castle (Rock In The Castle) in September 2005. The 1994-1995 line-up of Ginger, C.J., McCormack, and Ritch Battersby played at this gig.  Once again, the Wildhearts reformed in December 2006 and played a single live show at the Wulfrun Hall in Wolverhampton. This line-up saw Ginger joined again by C.J., Ritch Battersby and a new bassist, Scott Sorry (ex-Amen). This line-up soon became official, with plans made for a new album in 2007.
Question: What caused McCormack to need to get clean?
Answer: 

Background: The Roots is an American hip hop band, formed in 1987 by Tariq "Black Thought" Trotter and Ahmir "Questlove" Thompson in Philadelphia, Pennsylvania, United States. The Roots are known for a jazzy and eclectic approach to hip-hop featuring live musical instruments. Malik B., Leonard "Hub" Hubbard, and Josh Abrams were added to the band (formerly named "The Square Roots"). Since its first independent album-length release the band has released 10 studio albums, two EPs, two collaboration albums (with other artists), and also collaborated on recordings and in live shows with a wide variety of artists in many musical genres.
Context: The Roots' original lineup included Tariq "Black Thought" Trotter (MC) and Ahmir "Questlove" Thompson (drums), classmates at the Philadelphia High School for Creative and Performing Arts. As they began to play at school and on local streets, they added bassist Josh "The Rubberband" Abrams, who went on to form the jazz group The Josh Abrams Quartet. They later added another MC, Malik Abdul Basit-Smart ("Malik B.") and Leonard Nelson "Hub" Hubbard (bass), and Scott Storch (keyboards). Kenyatta "Kid Crumbs" Warren (MC) was in the band for Organix, the Roots' first album release. Another MC, Dice Raw, joined the band in cameo appearances on later albums. The band filled Storch's position with Kamal Gray (keyboards), who continues in that capacity. Kamal Gray did not play with the Roots on Late Night With Jimmy Fallon between April or May and early September 2012. His absence was not publicly explained, however on the September 17, 2012 (NBC's 'Late Night' 700th) episode, Gray returned to the group. Beatboxer Rahzel was a band member from 1995 to 1999. Alongside Rahzel was turntablist/vocalist Scratch, who also DJ'd in live concerts. However Scratch left abruptly in 2003. Malik B. left the group in 1999 due to personal reasons but continued to record, making occasional cameos on some albums. Guitarist Ben Kenney, had a brief stint with the group and contributed to the Phrenology album, but left to join Incubus as bassist. Percussionist Frank Knuckles joined the lineup in 2002 and guitarist Kirk "Captain Kirk" Douglas replaced Kenney. Vocalist Martin Luther toured with the Roots in 2003 and 2004 and contributed to the Tipping Point album. The group announced in August 2007 that its longtime bassist Leonard Hubbard was leaving. Owen Biddle was the band's bassist in 2007-2011.  The band announced on August 25, 2011 that Owen Biddle left the band, replaced by Mark Kelley. On The Tonight Show Starring Jimmy Fallon, James Poyser plays additional keyboards.  Because most of the band members hail from Philadelphia and its surrounding area, they showed their support for the Phillies during the 2009 World Series against the Yankees, displaying Phillies memorabilia when performing on Late Night with Jimmy Fallon. On the episode which aired the day after the Yankees clinched the title, Questlove stated "No comment!" on the show's intro (when he usually states the episode number), and had a Yankees logo purposely displayed upside-down on his drumset. In 2010, the group showed support for the Flyers during their run to the Stanley Cup Final by having the team logo on their drumset, and again in 2014 when the Flyers faced the New York Rangers in the first round of the playoffs on The Tonight Show Starring Jimmy Fallon.  In April 2017, Frank Knuckles left the Roots due to family issues, and has not appeared on The Tonight Show since then. Later in August 2017, Knuckles sued Questlove, Black Thought and the band manager Shawn Gee over unpaid royalties.  In June 2017, Questlove announced in an interview that producer and performer Stro Elliot is an official member of the Roots.
