"Johnny Rotten may have been the Sex Pistols' frontman, but once Glen Matlock was replaced by Sid Vicious, the bassist became as synonymous with the group – and punk in general -– as Rotten. However, he wasn't always a standard bearer for controversy, and this insightful film reveals how John Simon Ritchie became one of the scene's most infamous figures. Featuring previously unseen footage and interviews with a range of people from his life, from childhood friends to band colleagues, this documentary builds a more in-depth picture of an iconic figure."
