The Sex Pistols were an English punk rock band formed in London in 1975. Although they lasted just two-and-a-half years and produced only four singles and one studio album, Never Mind the Bollocks, Here's the Sex Pistols, they are considered one of the most influential acts in the history of popular music, initiated a punk movement in the United Kingdom, and inspired many later punk and alternative rock musicians. The first incarnation of the Sex Pistols included singer John Lydon (aka Johnny Rotten), lead guitarist Steve Jones, drummer Paul Cook and bassist Glen Matlock. Matlock was replaced by Sid Vicious early in 1977. Under the management of Malcolm McLaren, a visual artist, performer, clothes designer and boutique owner, the band provoked controversies that garnered a significant amount of publicity. Their concerts repeatedly faced difficulties with organisers and local authorities, and public appearances often ended in mayhem. Their 1977 single "God Save the Queen", attacking social conformity and deference to the Crown, precipitated the "last and greatest outbreak of pop-based moral pandemonium". Subjects addressed in their frequently obscene lyrics included the music industry, consumerism, abortion, violence, apathy, anarchy, fascism, the British Royal Family and the Holocaust.
