Although, Frank Sinatra Jr is the keeper of his father's music, it was said that he was not close to his dad and had spent most of his time in boarding schools.

"When I started as a kid, I wanted to be a piano player and songwriter. I only became a singer by accident. I was in college, playing in a little band. The lead singer got tanked one night. A guy in the band pointed at me and said, 'You sing.' I said, 'Me? Why me?' He said, 'You're a Sinatra, aren't you? Sing!'" he once said in an interview.
