BEIJING — After being interviewed by NBC following the United States' lopsided victory over Greece in Thursday night men's basketball action, Utah Jazz guard Deron Williams took time to sign a few autographs for the throngs of Chinese fans lining the nearby Olympic Basketball Gymnasium railings.

And he signed anything stuck in front of him — paper, game tickets, even an American flag.

However, he didn't hear the calls from one vocal fan to have the Utah Jazz guard and U.S. teammate Chris Bosh join him for some karaoke at a nearby bar later that night.

I'm all right, he smiled when asked about the karaoke invitation later. But when I play 'Rock Band,' I sing every now and then.
