LOS ANGELES — It's good news for Tim Urban and 23 other singers on "American Idol."

The 20-year-old college student from Duncanville, Texas, was among the 17 remaining semifinalists revealed Wednesday on the Fox singing competition after seven were unveiled Tuesday. Other semifinalists included 24-year-old sales representative Janell Wheeler from Tampa, Fla., and 24-year-old mother Crystal Bowersox from Elliston, Ohio.

Viewers may have noticed that shaggy-haired, 25-year-old shoe salesman Chris Golightly from Los Angeles was among the semifinalists on stage at the end of the episode, but it was Urban who was among the 12 dancing male semifinalists.

A Fox spokeswoman didn't immediately respond to clarify why Golightly was apparently replaced by Urban.
