Why 'Sex Pistols' ?
The name was suggested by their manager Malcolm McLaren. It was partly inspired by his clothing shop - SEX. He wrote in an essay in SPIN in Dec. 1988: "The name meant for me all sorts of things. It came about by the idea of a pistols, a pinup, a young thing, a better looking assassin, a Sex Pistol."
