Shaun recalled the glamour and challenges of growing up with parents in the spotlight, saying, "He was not a good father - and I don't say that with disrespect. I just say it with objectivity."
Meanwhile, Patrick Cassidy has continued the family's theatrical tradition, appearing on Broadway and in various iterations of the musical "The Music Man" alongside his mother, Shirley Jones. The youngest son, Ryan, has found success behind the scenes, working in the entertainment industry and publishing a children's book inspired by his own childhood.
