and all of its firework shows. In 2015, a new scene from Frozen was introduced, replacing the scene from "Brave", as part of the "Frozen Summer Fun" celebrations. On 10 November 2013, a full-length show titled "Disney Dreams! of Christmas" debuted. Hosted by Olaf, along with Anna from "Frozen", the show celebrates the winter season with several holiday-themed segments, featuring scenes from "Frozen", "Toy Story", "Bambi", "Fantasia", "One Hundred and One Dalmatians", "Mickey's Christmas Carol", "Lady and the Tramp", "Melody Time", and various vintage Mickey Mouse shorts. The show incorporates traditional holiday-related music, including "Carol of the Bells", "Let it Snow", "It's the Most Wonderful Time of the Year", "I'll Be Home for Christmas", "Believe", "Silent Night", the "Nutcracker Suite", "Jingle Bells", "I Have a Little Dreidel", "Feliz Navidad", "Joy to the World", and "Have Yourself A Merry Little Christmas" as well as Elsa's famous song "Let It Go". Joel McNeely composed the music for the show, which was performed by the London Symphony Orchestra, Cara Dillon, a children's choir and an adult choir. Some music pieces for the show are from the 2002 film "Return to Never Land", which he also scored. Key   The show is known to use a large amount of audio-visual, lighting, pyrotechnic and hydrotechnic technology. The show is controlled from a specially built control room, delivered by special convoy and themed as a small Victorian House in the central plaza, facing the castle. 70 km of fibre optics allow the show to be managed from this location. The show is operated by a main controller with three technicians to look after audio, video and special effects. However other technicians are placed at around the Castle to ensure the smooth running of the show, especially at the firing points. In total, twenty people are necessary at each performance.  16 Christie Projectors are used throughout the show to projection map onto the 2,500sqm castle which has been 3D scanned to create a computer model. Four projectors are installed on the roof of Main Street buildings, with an additional eight in purpose-built locations around the moat and viewing area. The other four are used to project onto the water screens either side of the moat.
