Ozzy Osbourne and wife were the guests of Greta Van Susten. So he wasn't invited by the Bush Administration? But would Administration be required to o.k. all guests?

If they did, it would only be to restrict those who threaten the safety of the President. This is not a WH function, so my guess is that the WH had no say-so in keeping liberals Harrison Ford, Glenn Close, and Serpenthead away from the event.
