Grand Poobah of “SNL,” wasn’t pleased by its “mawkish righteousness,” writes Susan Morrison in her new book “Lorne: The Man Who Invented Saturday Night Live,” out now.As Michaels’ longtime friend, singer/songwriter Randy Newman, told the author, “Lorne’s got a real old-fashioned, 1930s hard-boiled antenna for that kind of liberal bullshit.” It didn’t help that alumni Chris Rock, who came to early rehearsals to watch with Michaels, turned to the producer and asked, “Where are the jokes?”Rock joined host Dave Chappelle for the first scene after the Hillary/“Hallelujah” requiem, in which they played the only Black people (and the least surprised by Trump’s win) at a party of white millennials gathered to watch the election returns. When one stunned attendee declares, “This is the most shameful thing America has ever done,” both Chappelle and Rock burst out laughing.
