Sinatra Jr. followed his father into music as a teenager, eventually working for the senior Sinatra as his musical director and conductor. His father, the elder Sinatra, died of a heart attack May 14, 1998, at 82. Sinatra Jr. was able to provide a link to his father's music after his death, performing his father's songs and arrangements on tours and especially in Las Vegas. "Since my father's death, a lot of people have made it clear that they're not ready to give up his music," Sinatra Jr. told the AP interviewer. "For me, it's a big, fat gift to perform my dad's material. I get to sing with a big orchestra and get to sing orchestrations that will never be old." Sinatra Jr. was married in 1998, but divorced in 2000. He is survived by a son, Michael.
