Son of the legendary crooner Frank Sinatra who became a successful singer, songwriter, and conductor in his own right.
He became his father's musical director and conductor in 1988 at his father's request.
His kidnapping was rumored to have been arranged by his father in order to bring publicity to his son's singing career, a charge that was later found to be a falsehood. However, it did inspire the plot to Tiger by the Tail, a first-season episode of the long-running CBS police drama Hawaii Five-O starring Jack Lord.
He was kidnapped when he was 19 from room 417 at Harrah's Lake Tahoe and released after his father paid the ransom.
His father wasn't the only famous name in his family. His older sister Nancy Sinatra made her mark on the music industry, while his younger sister Tina Sinatra was content to work behind the scenes as a television producer.
