Def Leppard is a heavy metal and hard rock band from Sheffield, England, which formed in 1977 and has been identified as part of the New Wave of British Heavy Metal movement . The band consists of Joe Elliot (vocals), Phil Collen (lead guitar), Vivian Campbell (rhythm guitar), Rick Savage (bass guitar), and Rick Allen (drums) . The band has sold over 65 millions albums worldwide, and have two albums with RIAA diamond certification, Pyromania and Hysteria . In November, just prior to recording sessions for what would be a three-song release known as the Def Leppard EP, Kenning abruptly left the band . 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 . Def Leppard's debut album, On Through the Night, was released on March 14, 1980 . Although the album hit the Top 15 in the UK, many early fans were turned off by the perception that the band was trying too hard to appeal to American audiences[citation needed] by recording songs like "Hello America" and touring more in the US (supporting Pat Travers, AC/DC, and Ted Nugent). A performance at the Reading Festival in August (Iron Maiden also appeared) was marred when audience members expressed their displeasure by pelting the band with rubbish. Phil Collen, former guitarist with the glam band Girl, replaced Pete Willis, who was fired on 11 July 1982, due to excessive alcohol consumption on the job. (Willis would later resurface with the bands Gogmagog and Roadhouse.) This personnel change took place during the recording of their third album, Pyromania, which was released on 20 January 1983 and also produced by Lange. The lead single, "Photograph", turned Def Leppard into a household name, supplanting Michael Jackson's "Beat It" as the most requested video clip on MTV and becoming a staple of rock radio (dominating the US Album Rock Charts for six weeks). It also hit #12 on the pop charts. .
