Schmigadoon! season 2 takes Melissa, Josh, and viewers from the Golden Age musicals of the 40s and 50s to the darker musicals of the 60s and 70s that are parodied throughout. When Schmigadoon! was renewed for season 2, it was with the twist of a new setting and characters. While the core Schmigadoon! cast remained the same, with the exception of one actor who didn’t return from season 1, the Schmigadoon residents took on different roles to reflect the time period. As Schmigadoon! season 2 introduced viewers to the world of Schmicago, many musicals were parodied through songs, storylines, and characters.
