When does Schmigadoon! return?

The Apple TV+ series premiered July 16, 2021, starring an ensemble cast led by Cecily Strong and Keegan-Michael Key. The story centers around a couple from New York, both doctors, who become trapped in magical musical theatre settings and learn lessons about love and happiness. The first season, set in the bucolic small town of Schmigadoon, blends elements of various Golden Age musicals of the 1940s and '50s. The second season relocates the action to Schmicago and incorporates the darker, edgier themes of 1960s and 1970s musicals.
In the first season, two New York doctors, Melissa and Josh, go on a backpacking trip in an attempt to patch up their failing relationship, only to find themselves still arguing. The title and concept parody the 1947 musical Brigadoon. The name of the setting, Schmicago, parodies the 1975 musical Chicago.
