The old goat is at it again.
They weren't overselling Party Line; it was the most popular program on the air thanks to Verna Newell and Boyd Christianson. From her obit:
"Party Line" was an hourlong afternoon show broadcast live in front of a studio audience. Over the years, Newell welcomed then-Vice President Richard Nixon, actors Gregory Peck and Dustin Hoffman, singer Peggy Lee and boxer Joe Louis.
The show also featured an in-house organist, makeovers, crafty gift ideas and tips on how to stretch the family budget. Newell produced it and lined up the guests.
There doesn't seem to be any evidence of the show on YouTube. Stations care nothing for their history.
