The first incarnation of the Sex Pistols was singer Johnny Rotten (John Lydon), lead guitarist Steve Jones, drummer Paul Cook and bassist Glen Matlock. Matlock was replaced by Sid Vicious (real name John Ritchie) 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 what one commentator described as 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.
