Our subject today, Allen Swift, is better known for his work in radio & cartoons. In the latter, his credits included Underdog (as Simon Bar Sinister, among others), and some Gene Deitch-era Tom & Jerry shorts.
However, here's a rare case of Allen in front of the camera. After Buffalo Bob Smith suffered a heart attack, someone had to fill in as the voice of Howdy Doody, and Swift capably filled in. Here, in a rare case, Howdy introduces a professor, also played by Swift. Cowabunga!
