This is pretty cool: Disney's Frozen - "Let It Go" in 25 languages

This reminds me a lot of the great finale from Les Miserables: The Dream Cast in Concert, a production to celebrate its 10th Anniversary concert:

Encore #2: "Do You Hear the People Sing?" followed by "One Day More"

A little trivia related to Les Miserables:

• Colm Wilkinson, who is thought of as the quintessential Jean Valjean, appears as the Bishop in the 2012 movie version of Les Miserables.
• Lea Salonga, who plays Eponine in the 10th Anniversary performance, was the singing voice behind Jasmine in Disney's Aladdin and Mulan in Disney's Mulan and Mulan II. She later played Fantine in the 25th Anniversary performance of Les Miserables.
• Judy Kuhn, who portrays Cossette in the 10th Anniversary performance, was the singing voice behind Pocahontas in Disney's Pocahontas and Pocahontas II and Princess Ting-Ting in Mulan II.

ENJOY!
