Sid Vicious was suspected for the murder of his girlfriend Nancy Spungeon on October 12th of the same year. He served jail time but the case was never solved. He was found dead on February 1, 1979 after a heroin overdose (the heroin was supplied by his mother after he was released from jail). He was only 21.
The remaining Sex Pistols reunited in 1996 and released an album after touring. Glen Matlock returned as bass player.
Not particularly talented but captured the essence punk movement, despite actually being the artificial creation of entrepreneur Malcolm McLaren.
The band featured the spiky haired John Lydon, who would go on to form a band of musical merit (Public image Limited) and the completely talentless (though very controversial) Sid Vicious who topped his girlfriend and then himself.
