“Junie B. Jones, The Musical” opened at the John W. Engeman Theater in Northport this past Saturday to an audience filled with young children eager to see their favorite literary characters in the flesh, and with a fun, lively show, the cast did not disappoint.

The musical, based on the children’s book series by Barbara Park, follows the adventures of Junie B. Jones as she tackles life’s little obstacles she finds along the way in first grade. Among the many challenges she faces are losing her best friend, Lucille, to twins Camille and Chenille, finding out she needs glasses, and being unable to participate in the big kickball tournament. However, with the help of her family and friends, and jotting everything down in her Top-Secret Personal Beeswax Journal, the endearing redhead figures everything out and learns that when life hands you lemons you make lemonade.

Kate Keating is youthful and charming as the main character, Junie. As lead on many of the numbers, her clear soprano voice is perfect for revealing the story through song, and she easily draws the young audience in as she talks directly to them in a number of scenes.

Playing the role of mother, as well as fellow first-graders Grace and Sheldon, is Suzanne Mason whose stage presence as always is a strong one. The actress especially shines as the awkward, stuffy-nosed Sheldon, and she elicited loud giggles during a scene where Sheldon, ready to play the cymbals at the kickball tournament, experiences stage fright. Mason convincingly delivers the song “Sheldon Potts’ Halftime Show” as if she were a child herself.

Joshua Cahn plays Mr. Scary, Daddy and Gladys Gutzman, and it’s as Gutzman, the cafeteria lady, that Cahn takes center stage. The way he delivers the role is reminiscent of Edna Turnblad from “Hairspray,” and with funny lines and a cute dance number with Keating, he received well-deserved laughs and giggles from the audience members.

Michael Verre tackles dual roles as Junie’s new friend Herb and one of the twins, Chenille. While Verre is sweet as Herb, particularly during the number with Keating, “You Can Be My Friend,” he is hilarious as Chenille, where he good-naturedly dons a wig and dress, and gracefully sings and dances along with Camille and Lucille during the number “Lucille, Camille, Chenille” to the delight of the audience.

Jennifer Casey as Camille and Jose, Allie Eibeler as Lucille and Lennie, and Alyson Clancy as May and Bobbie Jean handle their role changes seamlessly, and no matter what part they are playing, effortlessly add to the fun and high energy of the musical.

Written by Marcy Heisler, with music by Zina Goldrich, “Junie B. Jones” features upbeat, fun-filled numbers that are perfect for a musical geared toward young children. Stand out songs in the first act include the opening number “Top-Secret Personal Beeswax” where Junie tells the audience all about her new journal, and at the end of the act, “Now I See,” where, with the help of her friends, Junie begins to like her new glasses. Act 2 also features the heartwarming number “Writing Down the Story of My Life” that will inspire little ones to record their adventures.

Directed by Jennifer Collester Tully, “Junie B. Junes, The Musical” is a journal-worthy theater experience for the whole family. The set is colorful, the actors are energetic, and the story is a relatable one for children. Most of all, the delightful story will warm the hearts of young and old.

The John W. Engeman Theater, 250 Main St., Northport will present “Junie B. Jones The Musical” through March 6. Tickets are $15 each. For more information, call 631-261-2900 or visit www.engemantheater.com.
