Frank Sinatra Jr dies aged 72
Frank Sinatra's son, Frank Jr, has died suddenly in Florida
The son of Frank Sinatra has died of a heart attack in Florida, shortly after complaining of feeling unwell before a concert.
Frank Jr, 72, cancelled his "Sinatra sings Sinatra" concert in Daytona before being taken to the Halifax Health Medical Center.
Helen Riger, the city’s cultural services and community events director, confirmed that Sinatra Jr. died earlier in the day. A family member said in a statement to the Associated Press that the singer died of cardiac arrest.
Sinatra Jr was the son of singer and actor Frank Sinatra and his first wife, Nancy, and brother of actress Nancy Sinatra and Tina Sinatra, a television producer.
Aged 19, he was kidnapped in Lake Tahoe, California in 1963 and was only released when his father paid $240,000 (£170,000) to his captors.
Sinatra was just starting his career in music at the time and was kidnapped. His career never reached the starry heights of the elder Sinatra, but he did act as conductor and musical director in the final years of his father's career.
Sinatra Jr was in Daytona Beach on Wednesday and set to perform his show, which would have included his renditions of his father's greatest hits as well as first-hand recollections of Ol' Blue Eyes.
The Daytona Beach News-Journal reported that he died at the Halifax Health Medical Centre. Sinatra Jr 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."
As news of his death spread, entertainers took to social media to pay their respects.
