The episode, which is entitled "The Workshop," is described as such: "Everything comes to a head as Eileen (Anjelica Huston), Derek (Jack Davenport) and the team present Marilyn The Musical to would-be investors. Ivy (Megan Hilty) is under pressure to perform, while her mother, Broadway star Leigh Conroy (special guest Bernadette Peters), undermines her at every turn. Karen (Katharine McPhee) must decide between the workshop and a meeting with a big-time music producer. Julia (Debra Messing) and Michael (guest star Will Chase) must face up to the consequences of their actions."

Prior to Follies, Bernadette Peters was last on Broadway in the revival of A Little Night Music. She received a 2003 Tony Award nomination for her performance as Rose in the Sam Mendes-directed revival of Gypsy.
