This is New York

Stewart made an appearance on this WCBS radio show on March 4, 1957. It received this listing in the New York Times:

NYT 3-4-57

Although the show is not available, it can be assumed that Stewart chatted with host Bill Leonard about his soon to be released film, The Spirit of St. Louis. The other guest of the program, Leland Hayward, was the producer of that film.
