Frank Sinatra Jr., the son of famed singer and actor Frank Sinatra, who carved out his own career as a singer and conductor, died on Wednesday of cardiac arrest at age 72, his sister said.
"The Sinatra family mourn the untimely passing of their son, brother, father, uncle, Frank Sinatra, Jr. of cardiac arrest while on tour in Daytona, Florida," his sister Nancy Sinatra said on her Facebook page. "Sleep warm, Frankie."
Sinatra was set to perform several of his father's songs at the Peabody Auditorium in Daytona Beach on Wednesday night, but the event was canceled when the singer fell ill, the auditorium said in a statement on Facebook.
"Frank Sinatra Jr. has passed away," it said. "Our love to his family and friends."
The Daytona Beach News-Journal reported that he died at the Halifax Health Medical Center. He told the newspaper recently that he never felt ashamed not reaching his father's level of fame.
"I think in my generation, when I came along in the early '60s, the type of music that was in vogue in society in those days had moved on to another kind of music," he told the News-Journal. "I was trying to sell antiques in a modern appliance store."
