In “Olaf’s Frozen Adventure,” a new 21-minute animated short from Walt Disney Animation Studios, the happy animated snowman teams up with Kristoff’s reindeer Sven for a merry mission to save Christmas for his friends. Anna and Elsa host a celebration for all of Arendelle as It’s the first holiday season since the castle gates reopened. As the townspeople left early to enjoy their individual holiday customs, the sisters realize that they do have their own family traditions. So, Olaf & Sven set out to comb the kingdom to bring home the best traditions for the Royal family. It’s “Frozen” so of course there are songs. You can now sing along with “When We’re Together,” thanks to a new lyric video. It’s one of four original songs written by Elyssa Samsel and Kate Anderson for the animated mini-feature. “When We’re Together” is performed by Idina Menzel, Kristen Bell, Josh Gad and Jonathan Groff, and is featured on the soundtrack, available now from Walt Disney Records. You can also hear three of the four songs in the short in the new finale at the Frozen sing-along at Disney’s Hollywood Studios.
