Disney+提前宣布续订《歌舞青春：音乐剧集》第四季。

　　Josh (Keegan-Michael Key) and Melissa (Cecily Strong) miss the magic they felt in Schmigadoon and in an attempt to return, find themselves in Schmicago—the reimagined world of ’60s and ’70s musicals. The new season will include new original musical numbers from co-creator and executive producer Cinco Paul, as well as returning stars Cecily Strong, Keegan-Michael Key, Ariana DeBose, Martin Short, Dove Cameron, Jaime Camil, Kristin Chenoweth, Alan Cumming, Ann Harada, Jane Krakowski, and Aaron Tveit with the addition of Tituss Burgess and Patrick Page.

跟随一对普通夫妇的不平凡故事，他们坠入爱河，发现共同寻找幸福的最大障碍可能就是他们自己。

这部音乐剧的故事发生在《油脂》的四年前;四个受腻了的弃儿敢于以自己的方式寻开心，引发了一场道德恐慌，这将永远改变Rydell高中。
