EAST HADDAM — Take twenty five songs made famous by Elvis Presley, mix them together with a William Shakespeare plot and add a dash of good old fashion musical comedy and what do you get? A delightful new production of All Shook Up, now running at Goodspeed Opera House under the direction of Daniel Goldstein. It returns to Connecticut, after making its debut at Goodspeed’s Terris Theatre twenty years ago.

All Shook Up was ahead of the curve when it came to so-called “jukebox musicals” on Broadway. A now common practice of taking a musical artist’s catalog and weaving a story around it, Mamma Mia perfected the form in 1999, while many pale imitations followed. Musicals from The Beach Boys, John Lennon, and even Johnny Cash failed to meet expectations.

Life on Broadway was short lived for All Shook Up, but it continues to be a perennial favorite. The new Goodspeed production is a shining example of why so many cherish this musical.

Loosely based on Shakespeare’s Twelfth Night, All Shook Up tells the story of a repressed town in the 1950s with an over the top authoritarian mayor who won’t allow singing, dancing, nor any general merriment. Chad, an Elvis-meets-Arthur Fonzarelli type, rolls into town and attempts to change the town’s way. All while navigating love triangles (or hexagons?) and singing and dancing his way into the hearts of the citizens. Featuring such Elvis hits as “Jailhouse Rock,” “Blue Suede Shoes” and “Can’t Help Falling in Love,” this show is musical comedy at its finest.

Ryan Mac has taken on the role of Chad. His enthusiasm, energy and command of the stage make him a joy to watch. His beautiful voice and skillful hip swinging are a nice added bonus. This musical tackles topics ahead of its time (in many ways) that one could worry didn’t age well, but Mac shows a skillful care in his handling of those scenes.

Falling for Chad is Natalie, a guys’ girl and the town mechanic, portrayed by Kerstin Anderson. Her chemistry with Mac is palpable and is the perfect balance. She gets some wonderful moments to show off her comedic abilities and powerful voice throughout the show.

Falling for Natalie is Dennis, played by Jordan Matthew Brown. While this show is full of hilarious moments, Brown gets the lion’s share. He squeezes laughs out of every moment he is on stage and those laughs are very well deserved.

Falling for Dennis is Miss Sandra, museum curator and a Mad Men-esque knockout played by Jessica Crouch. Crouch took a character that could be cartoony and simultaneously brought a groundedness and over-the-top-ness that was perfectly balanced.

Falling for Miss Sandra is Jim Haller, Natalie’s dad. Benjamin Howes returns to the Goodspeed stage after yukking it up last year in The Mystery of Edwin Drood. Howes brings humor and heart to the role.

Falling for Jim is Sylvia, the local bar owner, played on July 12 by understudy Montria Walker. The two of them are just wonderful together and Walker’s rendition of “There’s Always Me” was a highlight of the performance.

Finally, the uptight mayor Matilda and her sheriff sidekick Earl are portrayed by Amy Hillner Larsen and Kilty Reid, respectively. Larsen gets some of the funniest moments in the show with her Amy Sedaris-meets-Megan Mullaly portrayal of a mayor out to stop the roundabout and hold onto her power over the town. The only issue with her portrayal is that we don’t get more of her.

Kilty Reid gets an iconic moment near the end of the show that brings the house down. No spoilers. You’ll have to see it for yourself.

All Shook Up will have you singing and dancing in your seats all night long. If you are looking to get away and turn off your brain for a few hours to laugh and enjoy yourself, this is the place to do it.

Performances have been extended to August 24. In the words of Elvis Presley, “It’s now or never.” Tickets and more info can be found at goodspeed.org.
