Hank Williams Jr has enjoyed a 40-year career

A 19-year-old waitress had accused him of yelling obscenities and choking her at a Memphis hotel in March 2006.

District Attorney General Bill Gibbons would not say whether the waitress had decided to drop the case or if the parties reached a financial settlement.

Williams is the son of country legend Hank Williams, with a string of US hits including Family Tradition and All My Rowdy Friends Are Coming Over Tonight.

A lawyer hired by the waitress's parents demanded $250,000 (�127,000) from Williams two days after the alleged assault, but denied that the case was driven by money.
