"Fred’s family, his mother and sister are very sacred to him, a situation which has given rise to the false impression that he’s uncooperative. Mrs. Astaire (after seven years of marriage, he still refers to her as ‘my bride’) does not belong to the theatrical world, and Fred feels she should not be dragged into it for publicity purposes. He is very modest about his children. When little Freddy came on the set one day, big Fred just greeted him warmly with a ‘Hello, Son.’ But there was no concealing the look of pride in his eyes. When Eleanor Powell and I raved about the boy, Fred blushed a little and casually replied, ‘He is a nice boy, isn’t he?’"
