Variety reminisced that at the tender age of 24, Frank Sinatra Jr. had already performed in some 47 states and over a dozen countries.
Sinatra Jr. was close to Dean Martin's daughter Deanna during their lives, thanks to their fathers' involvement in the Rat Pack. Frank was still touring, and was actually in Daytone Beach, Florida because he was performing that same night.
Sinatra Jr. spent much of his childhood in his father's Palm Springs and Rancho Mirage homes, and, as an adult, he also often visited their summer home off Highway 74 west of Palm Desert.
"When you conduct an orchestra, all you are there to do is to follow that person and Sinatra was not an easy person to follow", Sinatra Jr. said. "We were all crying and singing".
Sinatra's father, 82, died in 1998 of a heart attack.
Sleep warm, Frankie... Sinatra was born on January 10, 1944 in Jersey City, NJ, the middle of three children that included older sister Nancy and younger sister Tina.
Frank Sinatra Junior, the son of legendary actor and singer Frank Sinatra, has died aged 72 in Daytona Beach, Florida. Sinatra Jr. would go on to create a fantastic musical career that continued right up until to his death.
His family said he died from cardiac arrest. "It was the only way I could get a job", he said.
The younger Sinatra was famously kidnapped at Lake Tahoe and held for ransom as a 19-year-old.
He was released two days later after his father paid the amount demanded by the kidnappers who also demanded all communication take place via payphone.
