They say the 60s died when the Manson Family butchered Sharon Tate and company, instantly making all the hippy folk ballads about peace and love that were popular at the time seem more than a little naive, and calling the mind-expanding benefits of LSD into question. Dropping acid might seem cute when you’re sitting around staring at multicoloured swirls, but it’s not so dandy when it also convinces you to hack random strangers to pieces in a bid to escalate an apocalyptic race war which you and your followers will survive by sheltering in a cave beneath Death Valley. Groovy? Not really. And furthermore you’ve ended an era, butter-fingers.
