Let It Go
Menzel broke onto the charts this year with her hit single "Let It Go" from the Disney animated musical Frozen.
Up Here will be staged by La Jolla Playhouse and directed by Alex Timbers.
The animated musical snowballs into a huge hit for Disney.
John Travolta may not know her name, but we do, and thanks to Jimmy, so does the late-night crowd.
The If/Then star originally performed the Oscar-nominated song as Elsa in the new Disney film.
