The younger Frank Sinatra Jr. died unexpectedly of cardiac arrest while on tour in Daytona Beach, Florida, (March 16, 2016, age 72). His real name was Francis Wayne Sinatra -- his father's full name was Francis Albert Sinatra -- but he went professionally by Frank Sinatra Jr. -- Francis Wayne Sinatra Junior, was the middle child of Frank Albert Sinatra and Nancy Barbara Sinatra, who was the elder Sinatra's first wife and the mother of all three of his children. Sinatra Jr.'s older sister was Nancy Sandra Sinatra, born June 8, 1940 in Jersey City, N.J., who had a successful musical career career of her own, and his younger sister was TV producer Christina - "Tina" - Sinatra born in Los Angeles, California on June 20th, 1948. Sinatra Jr. was born in Jersey City, N.J. in 1943, just as his father's career was getting started, and he would watch his dad become one of the most famous successful popular singers of all time. But he usually watched from a distance, as Sinatra was constantly away on tour engagements and was becoming a movie film star in Hollywood's feature film industry. Junior did, however, sometimes get to see him from the off side stage wings, especially when his father performed for long stints in Las Vegas. Sinatra Jr. was able to meet and see many other storied performers, too, such as Dean Martin, Sammy Davis Jr. and Count Basie. "I saw all the top stars perform," Sinatra Jr. told the AP in 2002. Junior said one of his favorite memories of his father was a show in the late 1960s at Caesars Palace in Las Vegas. "He was sitting on a little stool, and he sang the Beatles song 'Yesterday' and 'By the Time I Get to Phoenix' and 'Didn't We,' " Sinatra Jr. related. "We were all crying and singing.".
