Michael Imperioli played the tempestuous Christopher Moltisanti in "The Sopranos." He's co-authored a new book (along with Sopranos co-star, Steve Schirripa, who played Bobby Baccalieri) about their time on the show, "Woke Up This Morning: The Definitive Oral History Of The Sopranos." Bret and Michael discuss, at its core, what "The Sopranos" was all about, missing James Gandolfini, and the link Michael's character plays in the new prequel film, "The Many Saints Of Newark."
