The final season premiere of Fox's musical comedy features Rachel (Michele) returning to McKinley High School to help revive the New Directions glee club after it was disbanded by Sue Sylvester ( Jane Lynch). As she prepares to hang up a new sign-up sheet for auditions, she envisions herself singing the inescapable tune from Frozen on the stage in the auditorium.
The song's original singer, Idina Menzel, also plays Rachel's mother on the show.
Glee kicks off its final season Friday at 8/7c on Fox. Watch Michele's full performance of "Let It Go" below:
