Frozen proved to be one of the most successful and most loved animated films in recent history. What made the film more remarkable are the songs that came with it.

This year, D23 Expo, a Disney themed convention featured Kristen Bell at an event called Frozen FANdemonium in Anaheim, California. It was a musical celebration in honor of the Disney animated film.

Fans were clearly excited as Bell sang the popular Frozen track, “Do you Wanna Build A Snowman.”  The 35-year-old star was joined by the two girls who lent their voices for the film as younger Anna.

Katie Lopez, daughter of the composers of Frozen soundtrack, and Aggie Lee Monn, daughter of the director, played the younger versions of the character Anna. Seeing the three Anna in real life, sing on-stage was a very special treat for the fans present at the show.

Aside from “Do you Wanna Build A Snowman,” Bell also sung “For The First Time In Forever” and “The Spare” a song that was not included in the film.

The Frozen FANdemonium would not be complete without Olaf. The voice behind Olaf, Josh Gad, was also present at the event. He performed “In Summer.”

The concert ended with a magnificent rendition of “Let It Go” from the Frozen actors.

The video for Kristen Bell’s amazing performance immediately garnered thousands of views soon after it was uploaded on to their YouTube channel Inside the Magic. The musical celebration also featured the songwriters of the film, Kristen Anderson Lopez and Bobby Lopez.

Meanwhile, a short film titled Frozen Fever was released in March. The soundtrack from the 7-minute sequel was sung by Idina Menzel and Kristen Bell.
