Dave Grohl May Be Part Machine

James welcomes his guests Dave Grohl and Hilary Duff who have hung out at an undisclosed Halloween party. And James asks Dave how he manages to do everything that he does, from a bestselling book, touring, two inductions to the Rock & Roll Hall of Fame, a new film with his band and more. But one thing he couldn't do was get Vin Diesel in the Foo Fighters new slasher film, "Studio 666."
