HANNIBAL (REUTERS).- One hundred years after reports of his death were correct, not exaggerated, Mark Twain is a hot commodity again with an autobiography on the best-seller list and a new CD celebrating his legacy. The best seller is the first of the three-volume “Autobiography of Mark Twain,” the iconoclastic author’s private thoughts dictated during his life with the stipulation they not be published until he was dead for 100 years. That anniversary is 2010 and the 500,000-word book is flying off shelves. The CD, “Mark Twain: Words & Music,” is narrated by Garrison Keillor with Twain’s words spoken by Clint Eastwood. It also features songs by Emmylou Harris, Vince Gill, Brad Paisley, Ricky Skaggs and others
