Howdy Doody was a little before my time. I was a child of the 1960s being born in the late 1950s. So, I grew upon on Captain Kangaroo and Saturday morning cartoons and not on Howdy Doody.
FYI, did you know that Bob Keeshan, aka Captain Kangaroo was the original Clarabelle the Clown on Howdy Doody? Unfortunately for him Buffalo Bob fired him without warning at a public appearance. Fortunately for the rest of us his leaving Howdy Doody eventually led to his creation of Captain Kangaroo by which he taught and entertained children for almost 30 years.
