Mickey guest-directs a radio orchestra. The sponsor loves the rehearsal, but come the actual performance, Goofy drops all the instruments under an elevator, so they sound like toys. The sponsor hates it, but the audience loves it anyway.

The gang throws Mickey a surprise birthday party; his present is an electric organ, which Minnie plays while Mickey does a jazzy dance. Goofy bakes the cake, but keeps having trouble with it falling. The gang does a conga line to a Latin tune.

Mickey courts Minnie in the Gay Nineties: they take in a vaudeville show and go for a drive in his horseless carriage, to the strains of "While Strolling Through the Park" and "In the Good Old Summertime". Goofy rides by on a penny-farthing bicycle, and the whole Duck family rides by on a bicycle built for five.
