She was surprised!
March 26, 1958 -NBC airs “This Is Your Life, Donna Reed”.
Each week, an unsuspecting celebrity would be lured by some ruse to a location near the studio. The celebrity would then be surprised with the news that they are to be the featured guest. Next, the celebrity was escorted into the studio, and one by one, people who were significant in the guest's life would be brought out to offer anecdotes.
Donna believed she was to be a guest in a surprise tribute to producer Harry Joe Brown. Her entire family, along with old friends, teachers, and others from her past were reunited for the show.
