Decades ago, the Golden Age of Radio fulfilled the idol-making role in the U.S. Feinstein traces the phenomenon with archival clips of Bing Crosby, Cab Calloway, Kate Smith and others. He conducts one of the last interviews with TV and stage star Rose Marie ("Sally Rodgers" on "The Dick Van Dyke Show") and learns about her career as a child radio star. On his own radio program, Feinstein showcases virtuoso classical superstars, including violinist Joshua Bell and pianist Jeremy Denk. Finally, he discovers a lost radio program that featured Rosemary Clooney, and through digital magic performs a "new" duet with her.
