Problem: Background: The Sweet (also known as Sweet) is a British glam rock band that rose to worldwide fame in the 1970s. Their best known line-up consisted of lead vocalist Brian Connolly, bass player Steve Priest, guitarist Andy Scott, and drummer Mick Tucker. The group was originally called Sweetshop. The band was formed in London in 1968 and achieved their first hit, "Funny Funny", in 1971 after teaming up with songwriters Nicky Chinn and Mike Chapman and record producer Phil Wainman.
Context: Guitarist Mick Stewart joined in 1969. Stewart had some rock pedigree, having previously worked with The (Ealing) Redcaps and Simon Scott & The All-Nite Workers in the mid-1960s. In late 1965, that band became The Phil Wainman Set when the future Sweet producer joined on drums and the group cut some singles with Errol Dixon. In early 1966, Stewart left and later worked with Johnny Kidd & The Pirates. The Sweet signed a new record contract with EMI's Parlophone label. Three bubblegum pop singles were released: "Lollipop Man" (September 1969), "All You'll Ever Get from Me" (January 1970), and a cover version of the Archies' "Get on the Line" (June 1970), all of which failed to chart. Stewart then quit, and was not replaced for some time. Connolly and Tucker had a chance meeting with Wainman, who was now producing, and knew of two aspiring songwriters, Nicky Chinn and Mike Chapman, who were looking for a group to sing over some demos they had written together. Connolly, Priest and Tucker provided the vocals on a track called "Funny Funny" which featured Pip Williams on guitar, John Roberts on bass and Wainman on drums. The latter began offering the track to various recording companies. The band held auditions for a replacement guitarist and settled on Welsh-born Andy Scott. He had most recently been playing with Mike McCartney (brother of Paul) in the Scaffold. As a member of the Elastic Band, he had played guitar on two singles for Decca, "Think of You Baby" and "Do Unto Others". He also appeared on the band's lone album release, Expansions on Life, and on some recordings by the Scaffold. The band rehearsed for a number of weeks before Scott made his live debut with Sweet on 26 September 1970 at the Windsor Ballroom in Redcar. The Sweet initially attempted to combine various musical influences, including the Monkees and 1960s bubblegum pop groups such as the Archies, with more heavy rock-oriented groups such as the Who. The Sweet adopted the rich vocal harmony style of the Hollies, with distorted guitars and a heavy rhythm section. This fusion of pop and hard rock would remain a central trademark of Sweet's music and prefigured the glam metal of a few years later. The Sweet's initial album appearance was on the budget label Music for Pleasure as part of a compilation called Gimme Dat Ding, released in December 1970. The Sweet had one side of the record; the Pipkins (whose sole hit, "Gimme Dat Ding", gave the LP its name) had the other. The Sweet side consisted of the A- and B-sides of the band's three Parlophone singles. Andy Scott appears in the album cover shot, even though he did not play on any of the recordings.

Background: The Rolling Stones are an English rock band formed in London, England in 1962. The first stable line-up consisted of Brian Jones (guitar, harmonica), Mick Jagger (lead vocals), Keith Richards (guitar, backing vocals), Bill Wyman (bass), Charlie Watts (drums), and Ian Stewart (piano). Stewart was removed from the official line-up in 1963 but continued as a touring member until his death in 1985. Jones left the band less than a month before his death in 1969, having already been replaced by Mick Taylor, who remained until 1974.
Context: Since their formation in 1962, the Rolling Stones survived multiple feuds and have gone on to release 30 studio albums, 13 live albums and 109 singles. According to OfficialCharts.com, the Stones are ranked the fourth bestselling group of all time, with their top single being "(I Can't Get No) Satisfaction", regarded by many at the time as "the classic example of rock and roll." The Stones have also contributed to the blues lexicon, creating their own "codewords" and slang, which they have used throughout their catalog of songs, including some of their more popular songs. The band has been viewed as the musical "vanguard of a major transfusion" of various cultural attitudes, making them accessible to youth in both America and Britain. Muddy Waters was quoted as stating that the Rolling Stones and other English bands enhanced the interest of American youth into blues musicians; after they came to the United States, sales of Waters' albums - and those of other blues musicians - increased with public interest, thus helping to reconnect the country with its own music. The Rolling Stones have sold over 240 million albums worldwide and have held over 48 tours of varying length. The Stones have also held three of the highest grossing tours of all time, Bridges to Babylon, Voodoo Lounge, and A Bigger Bang. In May 2013, Rolling Stone declared them the "most definitional band that rock & roll has produced," with the Telegraph stating that Mick Jagger was "the Rolling Stone who changed music". The band has been the subject of numerous documentaries and were inducted into the Rock and Roll Hall of Fame by Pete Townshend in 1989. The Rolling Stones have inspired and mentored new generations of musical artists both as a band and individually. They are also credited with changing the "whole business model of popular music." The band has received - and been nominated for - multiple awards during their 55 years as a band; including three Grammy awards (and 12 nominations), the Juno award for International Entertainer of the Year in 1991, U.K.'s Jazz FM Awards Album of the Year (2017) for their album Blue & Lonesome, and NME awards such as best live band and the NME award for best music film, for their documentary Crossfire Hurricane.
