“Schmigadoon!” is a loving parody and an even more loving tribute to classic Broadway and Hollywood musicals, from “Oklahoma” to “The Music Man,” “The Sound of Music,” and the musical that inspired this title, “Brigadoon.” Each of the six episodes of around 30 minutes has Broadway-level singing and dancing, with tuneful, clever songs performed by some of the biggest stars from the Great White Way. The more you love musicals, the more you will love “Schmigadoon!”

Cecily Strong (“Saturday Night Live”) and Keegan-Michael Key (“Key and Peele,” “Keanu,” “Prom”) play surgeons who meet by a hospital candy machine and fall for each other. A few years later, their relationship is under some strain when they go on a couples hiking retreat. Lost in the rain, they happen on a cheerful 19th-century town where the citizens burst into song and elaborately choreographed dance numbers. They’re told by a magical leprechaun (Martin Short) that they cannot leave until they find true love.

The people they meet include Mayor Menlove (Alan Cummings), whose name could be a clue to his clear discomfort in a heteronormative community. Further discomfort could be the result of his dominating, judgmental wife Mildred (Kristin Chenoweth). (Compare them to Mayor Shinn and his wife Eulalie Mackecknie Shinn in “The Music Man.”) There’s the rapscallion carny Danny Bailey (Aaron Tveit). (Think Billy in “Carousel.”) and the teacher in the one-room schoolhouse, who lives with her lisping little brother (similar to Marion and Winthrop Paroo in “The Music Man”). Later on, they meet a beautiful blonde countess (Jane Krakowski) (compare to the Baroness in “The Sound of Music”) and a handsome, widowed doctor (Jaime Camil, a bit of Captain von Trapp). And there’s a pappy with a shotgun that he uses to protect his nubile young (how young?) daughters, including Dove Cameron as Betsy (maybe Daisy Mae in “Li’l Abner”).

Writers Ken Daurio and Cinco Paul are clearly the nerdiest of theater kids at heart and every bit of the series is imaginative, tuneful, thoughtful and detailed. Look behind the schoolteacher at the schedule of parent-teacher conferences on the blackboard. All the names are famous musical-creators. Some of the musical numbers are in direct conversation with classics, like Mildred’s solo, a witty riff on “Music Man’s” “Trouble.” Others are romantic or just pure fun.

Whether you are a theater nerd who can trace the history of the first act “I Want” song from “Show Boat” to “The Little Mermaid” or are just looking for a clever, warm-hearted, romantic adventure filled with supremely talented people giving their all, “Schmigadoon!” is one of 2021’s most delicious delights.

Parents should know that this movie has sexual references including out-of-wedlock pregancy and explicit language about reproduction and body parts, as well as relationship stress, strong language, and some alcohol.
