I’m told that David Geffen this summer is going to have a new guest along on that vacation cruise he’s organizing aboard his floating palace: Rupert Murdoch. Oh, to be a fly on the wall of that trip. Because whenever moguls get together at leisure, deals happen. Below is a photo of The Rising Sun, the 452 foot mega yacht which Geffen co-owns with software giant Oracle chief Larry Ellison. (C’mon, keep up: Geffen bought a half share for a reported $125M in the world’s No. 1 or No. 2 largest private boat 1 1/2 football fields long.) I’m told that the partner in DreamWorks SKG who’s worth $4.7 billion, and the News Corp chief worth $9 billion, kept in contact during Geffen’s quixotic quest to buy the Los Angeles Times. Murdoch tried to talk him out of it. I hear the New York Post and Times of London owner (whose Behemoth Media corp also owns print outlets around the world) Murdoch advised Geffen this about owning a newspaper: “Every day is going to be a headache for you. I’m used to these headaches. You’re not.” Meanwhile, Geffen’s office has denied reports that he was contacted by the union that represents the paper’s employees looking for a white knight billionaire to fend off Murdoch’s $5 billion bid for Dow Jones & Co and its Wall Street Journal. (The Independent Association of Publishers’ Employees wrote Ron Burkle, Warren Buffett and several others.) Given this budding friendship, I wonder what mergers and acquisitions Geffen and Murdoch cook up.
