Frank Sinatra Jr., who carried on his famous father's legacy with his own music career, and who was scheduled to perform in Daytona Beach and in St. Petersburg this week, has died.

He was 72.
The Sinatra family said in a statement to The Associated Press that Sinatra died unexpectedly Wednesday of cardiac arrest while on tour in Daytona Beach.
The statement said the family mourns the untimely passing of their son, brother, father and uncle. No other details were provided.

Kidnapped and held for ransom when he was 19, Sinatra Jr. had already followed his dad into the music business by then. He eventually worked for his father as his musical director and conductor. He performed the National Anthem at a New York Yankees game last year.

Sinatra Jr. was scheduled to perform Wednesday night at the Peabody Auditorium in Daytona Beach and at the Mahaffey Theater on Thursday.

A sign on the door at the Peabody Auditorium alerted ticketholders to the cancelled show. It read Tonight's Sinatra Show has been cancelled. Cash refunds are available from point of purchase. Credit refunds are automatic through Ticketmaster.
