News that Keith Richards is planning to write the first official Rolling Stones memoir raises a lot of questions.How will he remember all the stories? How will they all fit in a single volume? How will he explain that little joke about snorting his dad’s ashes? Intrigue like that usually drives the numbers higher when it comes to book deals, and such is the case with Richards’ tell-all. HarperCollins and Little, Brown were reported to be bidding for the tome with the payday reportedly exceeding $7 million. If a pact is done at that price, it would make the Stones guitarist one of the best-paid authors around. Bill Clinton‘s autobiography fetched north of $10 million in 2001.
