Kid Rock (search) was arrested Wednesday by Nashville police who are investigating a report that the entertainer punched a disc jockey at an adult entertainment club.

The singer was brought before Night Court Commissioner Howard Taradash at about 8:30 a.m.

Kid Rock was in handcuffs, and an officer was holding his hat. In answer to questions from the commissioner, the entertainer said he lived in Clarkston, Mich., and gave his birth date, Jan. 17, 1971.

He is charged with simple assault, a misdemeanor. Taradash set bond at $3,000 and Kid Rock remained in custody until bail could be posted.

The rapper laughed and joked with the two officers who arrested him and two others there for the hearing as he stood in the dock -- a small room with a large glass window that separates defendants from the commissioner and observers.

Authorities said Rock was charged after a 3 a.m. altercation at Christie's Cabaret near downtown.

"Inside the establishment there was a squabble concerning, I guess, the selection of music," Nashville police Sgt. James Smith told reporters. "Again there are no major injuries but an assault did take place."

Television footage from outside the club showed the DJ, identified as Jay Campos, with a red mark on his face and holding his broken eyeglasses.

Kid Rock was among entertainers who sang at a Tuesday memorial service at Ryman Auditorium for songwriter and promoter Merle Kilgore (search). The rapper, who has performed with several Nashville music figures including Hank Williams Jr. (search), strummed a guitar and sang "I Saw the Light" at the funeral.

Born Bob Ritchie, Kid Rock was a Detroit-area hip-hop DJ when he broke through with 1998's "Devil Without a Cause," which successfully married hard rock beats with rap lyrics.
