On the final week of the show James enlists two legends of the stage and screen in Jane Krakowski and Josh Gad to perform one last musical in the crosswalk on Beverly Blvd. in front of CBS. With tunes from "There's No Business Like Show Business," "Singin' In The Rain" and "La La Land" the trio pays homage to the industry. And a very emotional Josh, appearing in his fourth Carpool, isn't prepared for the level of goodbye he must face.
