So far, the invitees to my soiree are all well-known, in and well beyond their fields, but don't have super-celebrity status.
By "super-celebrity," I mean someone whose death would bring the media flocking to home or hospital (Michael Jackson), someone whose activities would rate the whole hour on Larry King. Someone like Oprah, whose appearance on TV commands millions of viewers.
He's very, very well known. Your answer is?
