"Pretty Vacant" was the third single released by the punk rock band Sex Pistols. This ode to anarchy was released on July 1, 1977. The song marked the band's only appearance on the British music show Top of the Pops. Also, according to Glen Matlock the riff was inspired by "S.O.S." by ABBA after hearing it on the radio. The song is particularly notable for John Lydon's (highly likely intentional) pronunciation of vacant with the clipped -ant producing a word much like the obscenity cunt.
