Mickey’s Amateurs (film) Mickey Mouse cartoon; released on April 17, 1937. Walt decided to try using some fresh directors, with storymen Pinto Colvig, Walt Pfeiffer, and Ed Penner handling the chores for this cartoon. When Donald’s recitation is booed off Mickey’s radio broadcast, Clara Cluck sings, Clarabelle plays the piano, and Goofy performs as a one-man band. But despite these diversions, Donald is back at the end with his recitation.
