Rotten was part of a pre manufactured band. The very antithesis of what punk was supposed to be. For punk see The Buzzcocks and the rest.................................imbeciles
It's hard to explain to people in the 21st century how much impact releasing a song like "God Save The Queen" in her silver jubilee year had at the time. Seems daft now, but a lot of people, including many in the media, thought the Sex Pistols were a genuine threat to the establishment. They weren't, obviously, but for a while it seemed like they were. Hence anybody who walked around dressed like a punk rocker in 1977 ran a sizeable risk of getting their heads kicked in.
I was a semi kinda punk, I was in London from 1977-1978 when I was 17 and perfect punk material, unfortunately I was in Basic Training at the time and it's hard to be a real punk in the Army, especially with a skinhead.
