Bill Carlson hosts a one hour special on the animals and features of the newly opened Minnesota Zoo.
Howard Salwasser: I have a question. What day did WCCO switched to the circle 4 logo? Looking at this video, and one Moore on Sunday video from June the same year, it looks as if the switch occured just after this special aired.
Eric Jon Magnuson: Since the video appears to show that The Betty White Show aired after the special, this may have actually been from late 1977.
