ROLLING STONE Keith Richards is amazed a bizarre story he made up about having his blood changed has survived for 35 years. The former heroin addict told reporters at a London airport in 1973 that he was travelling to Switzerland to have his blood transfused as part of treatment to help him kick drugs. The journalists believed the Brown Sugar rocker and his made-up story has flourished ever since. Richards says, "I started that myth, I was in Heathrow in 1973 on my way to a Swiss clinic - these were the days before the word rehab had ever been used. I was going to sort myself out. "These guys in raincoats (journalists) wanted to know what I was doing. I just threw the words out, 'I'm gonna get my blood changed.' It stuck. It became real. I never had my blood changed, I just got clean."
