“Captain Kangaroo:” Why Everyone Was Enchanted By This Show
Not All of Keeshan’s Shows Were Successful

“Mistor Mayor” was another of Bob Keeshan’s children’s programming ideas, though the show was not as well loved as “Captain Kangaroo” and it was not on the air for very long. In fact, when the show was canceled in 1965, some of the characters joined the “Captain Kangaroo” gang. They included Dudley D. Dudley, Rollo the Hippopotamus, and Aunt Maude.
Keeshan must have been disappointed when his most popular role show was canceled, right?
