Tom Farley, older brother of comedian Chris Farley, is the co-author (with Tanner Colby) of "The Chris Farley Show: A Biography in Three Acts." He tells Jim Fleming that the young Chris was always funny, but was funnier when he was sober. He developed a problem with alcohol as soon as he started drinking, which eventually led to his early death from substance abuse. And of course we hear clips from Chris in his glory years.
