The First Easter Rabbit, then, comes across as just another treacly R-B holiday cartoon. Debuting on NBC in 1976, with subsequent repeats airing on CBS, it's virtually been lost to the mists of time. Something tells me it didn't do so well in the ratings, such that NBC gave it up, and then, CBS did, too.
Burl Ives narrates, with a supporting cast including vets Bob McFadden, Paul Frees, & Don Messick, plus Stan Freberg and Robert Morse. In fact, this would be the beginning of Morse's association with R-B, which would last up through 1979's Jack Frost.
If it were redone today, it'd be expanded to an hour to better interpret the plot.
