Fun and Fancy Free
Disney had provided the voice for Mickey Mouse since his debut in 1928, and "Fun and Fancy Free" was the last time he would voice the role regularly, as he no longer had the time or energy to do so. Disney recorded most of Mickey's dialogue in the spring and summer of 1941. Sound effects artist Jimmy MacDonald would become the character's new voice actor, starting in 1948. Disney, however, did reprise the role for the introduction to the original 1955–59 run of "The Mickey Mouse Club".
Astor Radio Corporation
During 1933, Astor produced the first of its “Mickey Mouse” series of radios, and in 1936 introduced its first Bakelite Mickey Mouse radio, with a cartoon of the famous rodent on the dial. Early brochures featured a picture of Walt Disney and the mouse giving their "seal of approval". However, that was not done with permission from the Walt Disney Company and Astor became involved in a long-running court battle with Disney over the use of the Mickey Mouse name. The result was that Astor was forbidden to use the name "Mickey Mouse" for its radios, but it continued to produce the “Astor Mickey" radio for the next 16 years.
