Problem: Background: Cheryl Ann Tweedy was born in Newcastle upon Tyne on 30 June 1983, and grew up on council estates in the suburbs of Walker and Heaton. She is the fourth of five children of Joan Callaghan, and the first of her two children with Garry Tweedy following the collapse of her marriage to the father of her three other children.

Context: In 2004, Girls Aloud released a cover of The Pretenders' "I'll Stand by You" as the official single for the BBC's charity telethon Children in Need. In 2007, the group announced a joint release of Aerosmith and Run DMC's "Walk This Way" with Sugababes as the official single for the UK's other major charity telethon Comic Relief. The song was recorded at Comic Relief co-founder and trustee Richard Curtis' request.  In March 2009, Cheryl climbed Mount Kilimanjaro in aid of Comic Relief. The climb, organised by Gary Barlow, was also undertaken by fellow Girls Aloud member Kimberley Walsh, as well as Alesha Dixon, Fearne Cotton, Denise Van Outen, Chris Moyles, Ben Shephard, Ronan Keating and Barlow himself. Between 3 February and 23 March 2009, Cheryl, Walsh, Barlow, Moyles and Cotton also raised money for Comic Relief by providing the voice for the BT Speaking Clock. All nine celebrities reached the summit of Kilimanjaro on Saturday, 7 March 2009. Cheryl, along with Cotton, Van Outen and Shephard, reached the summit first at sunrise. The trek raised PS3.5 million for the charity. In February 2011, Cheryl launched her own charitable foundation with The Prince's Trust following a meeting with The Trust's President, HRH Charles, Prince of Wales. The Cheryl Cole Foundation is meant to provide vital funds for The Trust in the North East, which was set up to help disadvantaged young people from Cheryl's region. On 13 June 2011, she auctioned 20 dresses with ASOS to raise funds for the foundation.  In September 2011, Cheryl became the latest "Forces' sweetheart" when she visited British soldiers in Afghanistan. On 23 January 2015, Cheryl announced the launch of a second charity, once again alongside The Prince's Trust. The charity was named Cheryl's Trust, and was set up with the aim of raising PS2 million to build a centre, which will support up to 4000 disadvantaged young people in her native city of Newcastle. To raise these funds, Cheryl has thus far teamed up with Prizeo in March 2015, setting up a styling session competition, and also launched a limited edition Belgian Chocolate Bar with Greggs in August 2015; 5p proceeds from each sale being donated towards the trust. In November 2016, she became the ambassador of the charity ChildLine.

Problem: Background: The Nitty Gritty Dirt Band, an American country rock band, has existed in various forms since its founding in Long Beach, California in 1966. The group's membership has had at least a dozen changes over the years, including a period from 1976 to 1981 when the band performed and recorded as the Dirt Band. Constant members since the early times are singer-guitarist Jeff Hanna and drummer Jimmie Fadden. Multi-instrumentalist John McEuen was with the band from 1966 to 1986 and returned during 2001 departing once again in November 2017.
Context: The Nitty Gritty Dirt Band was founded around 1966 in Long Beach, California by singer-guitarist Jeff Hanna and singer-songwriter guitarist Bruce Kunkel who had performed as the New Coast Two and later the Illegitimate Jug Band. Trying, in the words of the band's website, to "figure out how not to have to work for a living," Hanna and Kunkel joined informal jam sessions at McCabe's Guitar Shop in Long Beach. There they met a few other musicians: guitarist/washtub bassist Ralph Barr, guitarist-clarinetist Les Thompson, harmonicist and jug player Jimmie Fadden, and guitarist-vocalist Jackson Browne. As Nitty Gritty Dirt Band, the six men started as a jug band and adopted the burgeoning southern California folk rock musical style, playing in local clubs while wearing pinstripe suits and cowboy boots. Their first paying performance was at the Golden Bear in Huntington Beach, California.  Browne was in the band for only a few months before he left to concentrate on a solo career as a singer-songwriter. He was replaced by John McEuen on banjo, fiddle, mandolin, and steel guitar. McEuen's older brother, William, was the group's manager, and he helped the band get signed with Liberty Records, which released the group's debut album, The Nitty Gritty Dirt Band during 1967. The band's first single, "Buy for Me the Rain," was a Top 40 success, and the band gained exposure on The Tonight Show Starring Johnny Carson, as well as concerts with such disparate artists as Jack Benny and The Doors.  A second album, Ricochet, was released later during the year and was less successful than their first. Kunkel wanted the band to "go electric", and include more original material. Bruce left the group to form WordSalad and Of The People. He was replaced by multi-instrumentalist Chris Darrow.  By 1968, the band adopted electrical instruments anyway, and added drums. The first electric album, Rare Junk, was a commercial failure, as was their next, Alive.  The band continued to gain publicity, mainly as a novelty act, making an appearance in the 1968 film, For Singles Only, and a cameo appearance in the 1969 musical western film, Paint Your Wagon, performing "Hand Me Down That Can o' Beans". The band also played Carnegie Hall as an opening act for Bill Cosby and played in a jam session with Dizzy Gillespie.
Question: DId they experience any other significant changes in the band during this period?

He was replaced by John McEuen on banjo, fiddle, mandolin, and steel guitar.
