Vivi Janiss was one of the radio era's most versatile and talented actresses, and she lent her voice to roles in comedies, westerns, thrillers, and everything in between. We'll hear her on a long car ride with her husband and an armed fugitive in "Backseat Driver" (originally aired on CBS on July 19, 1955), and she plays the wife of a man about to be executed in "Waiting" (originally aired on CBS on October 2, 1956). Plus, she appears in a dual role as a pair of twin sisters at the center of a mystery in "The Dancing Hands" from The Adventures of Philip Marlowe (originally aired on CBS on March 19, 1949).
