The Hardy Boys & Nancy Drew Mysteries was an ABC prime time series starring Parker Stevenson and Shaun Cassidy that first aired on Sunday, January 30, 1977. The Hardy Boys alternated with Nancy Drew, and once every fifth week in January and February 1977 with The Brady Bunch Hour. In the second season, the Hardys were joined by Nancy Drew (played by Pamela Sue Martin and, later, Janet Louise Johnson) for some episodes. Nancy was dropped altogether in the fall of 1978. The show went for three seasons with forty-six episodes, including 28 Hardy Boys episodes, 10 Nancy Drew only episodes, and 8 Hardy Boys/Nancy Drew cross-over episodes; the show went off the air in January 1979.
Most of the Hardys' friends never made regular appearances in the show, although Chet Morton did show up twice in the first season, while Callie Shaw was featured as Fenton's part-time office assistant.
