Matthew Sardo spoke with musician and writer Duff McKagan about his new book "How To Be A Man (and other Illusions)," the state of rock & roll, and if Guns N' Roses will ever get back together. Duff McKagan played bass for Guns N’ Roses for twelve years and co-wrote many of their most iconic songs. The band was inducted into the Rock and Roll Hall of Fame in 2012. Duff formed Velvet Revolver with his former band mate Slash and fronts his own band, Loaded. He writes weekly columns for Seattleweekly.com and ESPN.com. McKagan lives in Seattle with his wife, supermodel Susan Holmes McKagan, and their two daughters.
