Houston was supposed to be on a comeback tour, but instead she's being told never to come back. The artist's performance was called "a national scandal" by London's Independent, and she was booed in Australia.

Yes, try your best - and have a killer voice. Maybe Whitney Houston should consider bringing him in to do some of the heavy lifting on her besieged tour.
