VIDEO: Idina Menzel Sings 'Let It Go'; Gives Impromptu 'Defying Gravity' Performance at Disney 60 Taping

Last night, Disney lovers tuned in to ABC to watch Tony Award winner Idina Menzel perform the FROZEN mega-hit "Let It Go" as part of Disneyland's 60th Anniversary Special. What wasn't shown on air was Menzel's impromptu performance of "Defying Gravity" during the show's taping at Disneyland's California Adventure earlier this month.

After finishing her performance of "Let It Go," the IF/THEN star was about to leave when fans began singing the WICKED showstopper to her. Members of the band who knew the song began to play along and Idina, not wanting to disappoint, returned to the stage to sing. Check out both performances below!
