Dennis Day's sister-in-law

Actress Ann Blyth was married for over 50 years to James McNulty, the brother of singer and comedian Dennis Day. The McNultys had five children. There is a little irony in this. In the movie Top o' the Morning, Blythe starred opposite Bing Crosby. However, in the Lux Radio Theater adaptation of the film, Blythe was featured with Day as her romantic lead.
