Given the below context:  Pogoing aside, Vicious had been involved in a notorious incident during that memorable second night of the 100 Club Punk Special. Arrested for hurling a glass at The Damned that shattered and blinded a girl in one eye, he had served time in a remand centre—and contributed to the 100 Club banning all punk bands. At a previous 100 Club gig, he had assaulted Nick Kent with a bicycle chain. Indeed, McLaren's NME telegram said that Vicious's "best credential was he gave Nick Kent what he deserved many months ago at the Hundred Club". According to a later description by McLaren, "When Sid joined he couldn't play guitar but his craziness fit into the structure of the band. He was the knight in shining armour with a giant fist." "Everyone agreed he had the look," Lydon later recalled, but musical skill was another matter. "The first rehearsals...in March of 1977 with Sid were hellish.... Sid really tried hard and rehearsed a lot". Marco Pirroni, who had performed with Vicious in Siouxsie and the Banshees, has said, "After that, it was nothing to do with music anymore. It would just be for the sensationalism and scandal of it all. Then it became the Malcolm McLaren story".Membership in the Sex Pistols had a progressively destructive effect on Vicious. As Lydon later observed, "Up to that time, Sid was absolutely childlike. Everything was fun and giggly. Suddenly he was a big pop star. Pop star status meant press, a good chance to be spotted in all the right places, adoration. That's what it all meant to Sid." Westwood had already been feeding him material, like a tome on Charles Manson, likely to encourage his worst instincts. Early in 1977, he met Nancy Spungen, an emotionally disturbed drug addict and sometime prostitute from New York. Spungen is commonly thought to be responsible for introducing Vicious to heroin, and the emotional codependency between the couple alienated Vicious from the other members of the band. Lydon later wrote, "We did everything to get rid of Nancy.... She was killing him. I was absolutely...  Guess a valid title for it!
