In a newly released clip from his interview with 60 Minutes, Patrick Clancy reminisces about his children — Cora, Dawson and Callan — and their unique personalities. "At one point, [Cora] actually went to school and convinced her teachers that her name was Sofia because she loved Sofia the First so much," Clancy says. "Dawson was much more adventurous, much more daring. He was so funny. And he was so smart." "I mourn Callan in a way that I didn't really get to know him as well as my other kids."
