She also had begun to act again, mostly small featured parts in TV shows or the occasional movie, and by the early 1970s was in a perfect spot to take advantage of an offer from her ex-husband Jack Webb. He was putting together a new TV program called Emergency, and Julie soon found herself on a hit show, playing nurse Dixie McCall. (Ironically, her current husband, Bobby — who acted from time to time — was also given a role on her ex's show.) After Emergency's long run was over, Julie pretty much moved toward a quiet private life. She'd had three children with Bobby, so as the mother of five she had lots to enjoy and plenty to do. The years passed and by the late 1990s, she and Bobby were both in failing health. After 40 years together, he died in 1999 and she followed a year later.
So back to the original question. Was Julie London an actress who sang or a singer who acted? I think it comes down to an individual choice. Speaking for myself, I most remember Julie as a singer who could cast a spell over a listener — she certainly did that with me.
