The radio program starring William Bendix as Riley initially aired on the Blue Network, later known as ABC, from January 16, 1944 to June 8, 1945. Then it moved to NBC, where it was broadcast from September 8, 1945 to June 29, 1951. The supporting cast featured Paula Winslowe portraying Peg, Riley's wife, as well as John Brown, who portrayed not only undertaker "Digger" O'Dell but also Riley's co-worker Jim Gillis. (Brown also played the character of Waldo Binny.) Whereas Gillis gave Riley bad information that got him into trouble, Digger gave him good information that "helped him out of a hole," as he might have put it. Brown's lines as the undertaker were often repetitive, including puns based on his profession; but, thanks to Brown's delivery, the audience loved him. The program was broadcast live with a studio audience, most of whom were not aware Brown played both characters. As a result, when Digger delivered his first line, it was usually greeted with howls of laughter and applause from surprised audience members.
