Hank Williams Jr. got an enthusiastic reception at a concert in Knoxville, Tenn., a week after the country music star walked out on a performance.

About 12,000 people at the Thompson-Boling Arena at the University of Tennessee clapped, shouted and whistled Friday night during Williams' two-hour performance.Last week in Bristol, Tenn., Williams stormed off the stage without explanation after only 40 minutes. A spokesman said later that Williams had been ill. Viking Hall in Bristol banned Williams because of the walkout.
