A young Tracy Jordan is infiltrating Kabletown!
In the episode, Kabletown decides to discontinue "TGS" as a live show. While Liz and Jack don't mind, Kenneth does his best to convince the "TGS" staff that live episodes are worth it.
Here's where Glover comes in: According to executive producer Robert Carlock, Kenneth proves his point by reminding everyone of the history of "TGS." As a result, most of the episode consists of flashbacks to old shows featuring Glover as a young Tracy Jordan.
While this is the first time Glover will play a key role on "30 Rock," it's hardly his first stint on the NBC sitcom. In addition to a series of cameos, Glover was a writer on the series before landing his "Community" gig, and he also did the vocal work for an extended version of Morgan's Season 1 jingle, "Werewolf Bar Mitzvah."
“Tracy wasn’t available, so Donald came in and [performed the extra material],” Carlock told TVLine. “I don’t think you can tell. It’s pretty remarkable. All the spoken stuff is Donald doing Tracy.”
