Minnie's Yoo Hoo
Her next appearance was arguably more significant. Mickey's Follies (June 26, 1929), featured the first performance of the song "Minnie's Yoo Hoo". "The guy they call little Mickey Mouse" for the first time addresses an audience to explain that he has "Got a sweetie" who is "Neither fat nor skinny" and proudly proclaims that "She's my little Minnie Mouse". Mickey then proceeds in explaining his reaction to Minnie's call. The song firmly establishes Mickey and Minnie as a couple and expresses the importance Minnie holds for her male partner. Soon it would become the theme song to all of their series.
