You can have that “Sunday Morning Fever” even if it’s not Sunday.

And you may catch “Sunday Morning Fever,” one of the great production numbers in “Sister Act,” when you see the spectacular musical, through March 12, Civic Theater of Allentown.

The cast of 28, by my count, is across the boards excellent, energetic and in the moment as directed with brio, class and inventiveness by Will Morris, Civic Theatre Associate Artistic Director. You will be swept up by the songs, the performances and the story. This is stand-up-and-cheer theater. The Feb. 24 opening night performance was seen for this review.

You may be familiar with the storyline of the musical, based on the 1992 movie of the same title that starred Whoopi Goldberg as Deloris Van Cartier, who the police place in hiding as a nun at a Catholic church because she witnessed a murder. The musical is set in Philadelphia in 1977. The original 2011 Broadway production was nominated for four Tony Awards.

The musical has eight songs, including one reprise, in Act I, and 13 songs in Act II, with six reprises. The music is by Alan Menken (Oscar winner, “The Little Mermaid,” 1989; “Beauty and the Beast,” 1991, “Aladdin,” 1992) with lyrics by Glenn Slater (Tony nominee, “The Little Mermaid”) and book by Bill and Cheri Steinkellner (Tony nominee, “Sister Act”).

The Civic production has numerous talented actors, especially Deborah D’Haiti as Deloris Van Cartier. D’Haiti owns the role. She owns the stage in every scene that she is in. This is one the best musical theater performances by a female in years on the Lehigh Valley stage, community, college or professional.

D’Haiti is simply astounding and one of the main reasons to see the Civic show. From her opening number, “Take Me To Heaven,” backed by Miki Fuentes (Michelle) and Deja Frazer (Tina), D’Haiti projects confidence, audience engagement and a wonderfully powerful and nuanced singing voice.

As if one needs more convincing, and one doesn’t, D’Haiti, again with Fuentes and Frazer, backs that number up with the next number, “Fabulous, Baby!” D’Haiti brings the first act curtain down with “Raise Your Voice,” backed by the chorus of Nuns, of which, again by my count, are a discipleship of 12 fired-up, all-dancing, all-singing, all in full habit. The nuns are such fun and so gleeful.

D’Haiti continues the exuberance in Act II with the aforementioned “Sunday Morning Fever,” an obvious and clever response to the title of “Saturday Night Fever” (1977), the disco movie. Here, D’Haiti, along with Tracy Ceschin (Mother Superior); Dan Becker (Monsignor O’Hara), who is humorous throughout; Justan Parker (Eddie) and the Nuns, including Trish Kane Steele (Sister Mary Lazarus), in hilarious froggy voice throughout, present a terrific rendition that will make you want to stand up at your seat. Sample lyrics: “Boogie ‘til you feel your spirit move!/Come and get that/Sunday morning fever./Give the Lord a try!”

Also, in Act II, D’Haiti impresses with “Bless Our Show,” backed by the Nuns, and in her solo spotlight rendition of the title song, “Sister Act.”

Perhaps second to “nun” (Sorry, I couldn’t resist the pun.) is Tracy Ceschin as Mother Superior. Ceschin has the proverbial slow-burn react that can make strong men or women weak and she employs it to great effect. She is the rock of the show. Ceschin has a splendid voice, and she displays it with bravado in the aforementioned number and especially in the Act I solo reprise of “Here Within These Walls.” In Act II, she dials it down and then back up in “I Haven’t Got A Prayer,” which she sings beautifully and with panache.

Another standout is Nina Elias (Sister Mary Robert), who is quite fun in her role as a nun novitiate. Elias is superb and very moving in her bittersweet solo, ”The Life I Never Led.”

Justan Parker (Eddie) provides some comedic moments, as well as some smooth dance moves and a handsome and impressive voice in the winsome “I Could Be That Guy.”

The ensemble of Keith Miller (Curtis), Bob Trexler (Joey), Diego Subero (Pablo) and Dominique Shelby (TJ) is terrific in “When I Find My Baby.”

Music Director Veronica Cummings and Choreographer Deena Linn put the cast through its paces and all are up the task.

Will Morris is also Lighting Designer, creating impressive tableaus of street scenes, interiors and the church, working with Technical Director-Scenic Designer Luke Blomstrom, Scenic Artist Jan Joyce, Projection Designer Rick Frendt and Props Designers Todd Croslis, Maria Defebo-Edwards and Jason Sizemore.

Sound Designer is Randall Utsch. Costume Designer is Scaramouche Costumes, with Costume Coordinator Maggie Fajardo and Hair & Makeup Designer Kim Danish.

I cannot convey enough superlatives for Civic Theatre of Allentown’s production of “Sister Act.” To quote Mother Superior, “There are no words.”

The show can be recommended for the entire family. Yes, it’s irreverent. It’s also reverent. It’s fun and an inspiration. Whether you are a believer or not, you will absolutely love Civic’s “Sister Act.”
