With James Corden, the cast of “Frozen 2” steps into the unknown. After some trouble getting cast, they sing their songs on a crosswalk in Los Angeles.

James Corden asked the cast of Frozen 2 to sing for the people of Los Angeles on another episode of “Crosswalk: The Musical,” which is one of his most popular shows.

First, James wanted to play Elsa, but Idina Menzel showed that she was the better singer in a sing-off, so the group went out into traffic to sing their hearts out.
