The Disney Parks Blog reports that the musical number “Un Poco Loco” will anchor the new scene when it opens to guests at Disney California Adventure and Disneyland Paris on July 17, before being added to Magic Kingdom Park later this year during the Walt Disney World Resort 50th anniversary celebration.
The film’s fun, upbeat music and characters combined with the humor of Donald Duck marks the first time Disney and Pixar animators have worked on a creative endeavor where characters from both animation studios will be seen together on screen since 'Ralph Breaks The Internet.'
Because music is such an integral part of the show, we were also fortunate to tap one of the film’s original composers – the world-renowned Germaine Franco – to produce a “Coco” score unique to “Mickey’s PhilharMagic.” Guests will enjoy this new scene alongside all of the show’s current fan-favorite musical numbers.
