Pop star Michael Jackson greeted thousands of U.S. troops and their family members at a U.S. Army base in Japan Saturday. Jackson walked around shaking hands and exchanging words to thank them for their service. He told the crowd, “Those of you in here today are some of the most special people in the world. It is because of you in here today, and others who so valiantly have given their lives to protect us, that we enjoy our freedom.” Jackson, 48, arrived in Japan last Sunday for his second trip in less than a year to attend parties, including an extravagant gala where paying guests each laid down $3,500 for tickets. On Friday, he made an appearance at another party for his less well-off fans. Over 1,000 people crowded a popular night club. He did not perform at either party.
