IN: 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.

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.

input: On September 8, 2004, Rather reported on 60 Minutes Wednesday that a series of memos critical of President George W. Bush's Texas Air National Guard service record had been discovered in the personal files of Lt. Bush's former commanding officer, Lt. Col. Jerry B. Killian. Once copies of the documents were made available on the Internet, their authenticity was quickly called into question. Much of this was based on the fact that the documents were proportionally printed and displayed using other modern typographic conventions usually unavailable on military typewriters of the 1970s. The font used on the documents has characteristics that exactly match standard font features of Microsoft Word. This led to claims that the memos were forgeries. The accusations then spread over the following days into mainstream media outlets including The Washington Post, The New York Times, and the Chicago Sun-Times.  Rather and CBS initially defended the story, insisting that the documents had been authenticated by experts. CBS was contradicted by some of the experts it originally cited, and later reported that its source for the documents - former Texas Army National Guard officer Lt. Col. Bill Burkett - had misled the network about how he had obtained them.  On September 20, CBS retracted the story. Rather stated, "If I knew then what I know now, I would not have gone ahead with the story as it was aired, and I certainly would not have used the documents in question." The controversy has been referred to by some as "Memogate" and "Rathergate."  Following an investigation commissioned by CBS, CBS fired story producer Mary Mapes and asked three other producers connected with the story to resign. Many believe Rather's retirement was hastened by this incident. On September 20, 2007, Rather was interviewed on Larry King Live commenting "Nobody has proved that they were fraudulent, much less a forgery. ... The truth of this story stands up to this day."
