You can't be "Uptight" listening to classic hit songs that are "Signed Sealed Delivered" with fun! Yes, it's the Stevie Wonder tribute episode! 

Jenna and Kevin dive right in with fun behind-the-scenes stories like how Katey Sagal came to play Kevin's mom and what it was like working with her, being in complete awe of Amber Riley's performances, Kevin learning he was going to New York by reading it in a script (yep, no one told him), and their mental states during this stage of the show because of external factors like lower ratings and uncertainty about the show's future.
