IN: Def Leppard are an English rock band formed in 1977 in Sheffield as part of the new wave of British heavy metal movement. Since 1992, the band has consisted of Joe Elliott (lead vocals), Rick Savage (bass, backing vocals), Rick Allen (drums, backing vocals), Phil Collen (lead and rhythm guitar, backing vocals), and Vivian Campbell (rhythm and lead guitar, backing vocals). This is the band's longest lasting line-up. The band's strongest commercial success came between the early 1980s and the early 1990s.

Rick Savage, Tony Kenning, and Pete Willis, all students at Tapton School in Sheffield, South Yorkshire, formed a band called Atomic Mass in 1977. The band originally consisted of Willis on guitar, Savage on bass (after originally playing guitar), and Kenning on drums. Only 18 at the time, Joe Elliott tried out for the band as a guitarist following a chance meeting with Willis after missing a bus, in November 1977. During his audition it was decided that he was better suited to be the lead singer. Their first ever gig was in the dining hall in A Block in Westfield School in Mosborough, Sheffield.  The band adopted a name proposed by Elliott, "Deaf Leopard", which was originally a band name he thought up while writing reviews for imaginary rock bands in his English class (and in at least partial reference to Led Zeppelin). At Kenning's suggestion, the spelling was slightly modified in order to make the name seem less like that of a punk band. In January 1978, Steve Clark joined the band. According to Elliott, he successfully auditioned for the band by playing Lynyrd Skynyrd's "Free Bird" in its entirety.  In November, just prior to recording sessions for what would be a three-song release known as The Def Leppard E.P., Kenning abruptly left the band; he would later form the band Cairo. He was replaced for those sessions by Frank Noon. By the end of the month, Rick Allen, then only 15 years old, had joined the band as its full-time drummer. Sales of the EP soared after the track "Getcha Rocks Off" was given extensive airtime by renowned BBC Radio 1 DJ John Peel, considered at the time to be a champion of punk rock and new wave music.  Throughout 1979, the band developed a loyal following among British hard rock and heavy metal fans and were considered among the leaders of the new wave of British heavy metal movement. Their growing popularity led to a record deal with the major label Phonogram/Vertigo (Mercury Records in the US). Def Leppard's original management, MSB, a local duo consisting of Pete Martin and Frank Stuart-Brown, were fired after Martin and Joe Elliott got into a fistfight over an incident on the road. The band approached Peter Mensch of Leber-Krebs management, who had booked them on a tour of the UK supporting AC/DC. Mensch, who admitted that he had had his eye on the band, became their manager.

Did they keep their original members for those years?

IN: "Eight Miles High" is a song by the American rock band the Byrds, written by Gene Clark, Jim McGuinn (a.k.a. Roger McGuinn), and David Crosby and first released as a single on March 14, 1966 (see 1966 in music). Musically influenced by Ravi Shankar and John Coltrane, "Eight Miles High", along with its McGuinn and Crosby-penned B-side "Why", was influential in developing the musical styles of psychedelic rock, raga rock, and psychedelic pop. Accordingly, critics often cite "Eight Miles High" as being the first bona fide psychedelic rock song, as well as a classic of the counterculture era. The song was subject to a U.S. radio ban shortly after its release, following allegations published in the broadcasting trade journal the Gavin Report regarding perceived drug connotations in its lyrics.

The song's use of Indian and free-form jazz influences, along with its impressionistic lyrics, were immediately influential on the emerging genre of psychedelic rock. Accordingly, some authors and music historians, including Eric V. D. Luft, Domenic Priore, and Dwight Rounds, have described "Eight Miles High" as being the first bona fide psychedelic rock song. In his book Riot On Sunset Strip: Rock 'n' Roll's Last Stand in Hollywood, Priore cites "Eight Miles High" as being the record that kicked off the psychedelic craze, explaining "prior to 'Eight Miles High,' there were no pop records with incessant, hypnotic basslines juxtaposed by droning, trance-induced improvisational guitar."  The song was responsible for the naming of the musical subgenre raga rock, when journalist Sally Kempton, in her review of the single for The Village Voice, used the term to describe the record's experimental fusion of eastern and western music. However, although Kempton was the first person to use the term raga rock in print, she had actually borrowed the phrase from the promotional material that the Byrds' press office had supplied to accompany the "Eight Miles High" single release. In a 1968 interview for the Pop Chronicles radio documentary, McGuinn denied that the song was in fact an example of raga rock, while Crosby, speaking in 1998, dismissed the term entirely, stating "they kept trying to label us; every time we turned around, they came up with a new one ... it's a bunch of bullshit." Nonetheless, the experimental nature of the song placed the Byrds firmly at the forefront of the burgeoning psychedelic movement, along with the Yardbirds, the Beatles, Donovan and the Rolling Stones, who were all exploring similar musical territory concurrently.  Contemporary reviews for the single were mostly positive, with Billboard magazine describing the song as a "Big beat rhythm rocker with soft lyric ballad vocal and off-beat instrumental backing." Record World magazine also praised the song, commenting "It's an eerie tune with lyrics bound to hypnotize. Will climb heights." In the UK, Music Echo described the song as "wild and oriental but still beaty". The publication also suggested that with the release of "Eight Miles High" the Byrds had jumped ahead of the Beatles in terms of creativity, stating "[By] getting their single out now they've beaten the Beatles to the punch, for Paul [McCartney] admitted recently that the Liverpool foursome are working on a similar sound for their new album and single." In recent years, Richie Unterberger, writing for the Allmusic website, has described "Eight Miles High" as "one of the greatest singles of the '60s."  In 1999, the song was inducted into the Grammy Hall of Fame, an honor reserved for "recordings of lasting qualitative or historical significance that are at least 25 years old." In 2004, Rolling Stone magazine ranked "Eight Miles High" at number 151 on their list of The 500 Greatest Songs of All Time and in March 2005, Q magazine placed the song at number 50 on their list of the 100 Greatest Guitar Tracks.
