I loved this classic children's show because it was gentle. My aunt even nicknamed Bunny Rabbit "Bun Bun".
The show changed in the 1970's with the addition of Debbie Weems as well as a new theme song, Good Morning Captain. Even the opening had famous people wishing the Captain good morning (one opening had Brett Somers, Charles Nelson Reilly, Richard Dawson, Gene Rayburn & Johnny Olsen from Match Game 7X).
Another reason I get a laugh out of the Captain when Mr. Moose would drop ping pong balls on the Captain. Remote Control did that on an episode & Ken Ober quipped, "We owe a residual to Captain Kangaroo!"
But when the 1980's came, it would be the end. CBS had to get into the morning news band wagon & bump the Captain early in the morning, followed by weekends. That version was later seen in reruns on PBS.
Wonderful series overall!
