Well, the bulk of this history was written a year or two ago when I had been emersing myself in everything Sex Pistols. For the most part, I'm assuming I've gotten my dates right, but I wouldn't count on it. If you are trying to do actual research on the history of the Pistols, feel free to use anything here but double check any dates you are planning on using.
Here's Some books on the Sex Pistols, at least ones that I have read. There's always tons of article and information on the Pistols though, but don't trust it all, because depending on the author the story changes. Click on the book and it will take you to the Punk77 description, because I'm not taking the time to write indivisual descriptions
