Tonight, I watched the 1971 Rankin/Bass special, "Here Comes Peter Cottontail." It's possible I might have seen it decades ago, but I hadn't seen it recently. Casey Kasem provided the voice of Peter, so I kept expecting the rabbit to turn to the camera and say, "And the eggs are now delivered. Now, on with the countdown..."
Once you've heard Kasem's delivery on "American Top 40," you don't forget his distinctive cadence.
