Corcoran appeared in a Mouseketeer outfit with the name Moochie across his chest just once. In "Disneyland: The Fourth Anniversary Show" (1957), "Mouseketeer" Moochie repeatedly badgers Walt Disney for information about "Zorro". Also on the fourth anniversary show, aired on September 11, 1957, segments were shown of "Rainbow Road to Oz", a live-action film about characters in the Land of Oz. Inspired by L. Frank Baum's Oz books, the film was to star some of the Mouseketeers, including Darlene Gillespie as Dorothy and Annette Funicello as Ozma, as well as Tommy Kirk and Corcoran.
