His live HBO special, scheduled for last Sunday, was postponed. The event was supposed to boost the King of Pop’s flagging career. Instead, cynics made the most of the news. Record stores played promos for Jackson’s ailing “HIStory” album. A Portland, Ore., radio-station intern posing as President Clinton called Jackson and played the conversation on the air. (Jackson complained of dizziness, but wished the First Family well.) And as bodyguards unloaded Jackson’s Shirley Temple posters, reported the New York Post, one bystander joked, “Who are they bringing in next–Buster Brown?” Some fans outside the hospital were not amused.
