The orchestra is performing the William Tell overture, but then Donald Duck (in his third appearance in a Mickey cartoon) appears selling ice-cream. Uninvited, Donald takes out his flute and distracts the band into playing Turkey in the Straw.
The cartoon is notable for being the first Mickey Mouse film in Technicolor, although two more Mickey cartoons were made in black and white before they were produced in colors on a permanent basis; Mickey's Service Station and Mickey's Kangaroo.
