Add Lyor, plus Julie

THAT’S WHAT FRIENDS ARE FOR: The brief final chapter in Cohen’s colorful Warner narrative apparently came as a surprise to Lyor, despite the fact he had just a few months left on his deal. Insiders say that it came down to a difference in business philosophy between Cohen and Len Blavatnik, who agreed to disagree in their final conversation, which went down last Sunday, the day before the announcement of his departure. In related chatter, some are contending that should Julie Greenwald choose to stay at WMG in a post-Cohen world, her role could be more expansive than before. (10/8a)
