Mickey Mouse Clubhouse: Mickey's Big Band Concert(NaN)

Mickey and friends practice their band's music for the Mickey Park Polka-Palooza Dance Festival where the elephants will dance the Pachyderm Polka. (The Sensational Six: Mickey on ukulele, Donald on tuba, Minnie on piano, Daisy on xylophone, Goofy on trombone, and Pluto as metronome), but their instruments need to be fixed (Minnie's Piano have the wrong pitch, Goofy's trombone slide is stuck, Daisy's xylophone is falling apart, Mickey's ukulele strings are out of tune, Donald's papers blow away).
