There's nothing terribly wrong with Country Dinner Playhouse's production of Guys and Dolls, but not much feels right. The biggest triumph of opening night, in fact, should never have happened.

Two nights before opening, the show's two female leads, Sharon Kay White and Tamara Jenkins, had a head-on collision when one went up the wrong ramp. Jenkins suffered a concussion, and in her place, Barnstormer and understudy Sara Seever tackled the role of Sarah Brown at the opening.

Tackled may not be the right word. Seduced would be better. Or charmed into submission. Seever took the stage as if she'd been performing the role for weeks, applying a delicate voice that matched the Salvation Army bell her character chimes. This actress is fully capable of playing a leading role.

Other, more experienced, hands were capable singers and performers but woefully miscast. The show's memorable ode to chemistry went unnoticed, and few sparks fly under Paul Dwyer's direction.

It's a surprising thing, since the show is otherwise charming, from the masterful choreography of Kitty Skillman Hilsabeck to what has become an impressive roster of male dancers ( again, Robert Hoppe and Rob Costigan exceed the size of their roles).

Jay Montgomery has a fine voice and attractive air, but lacks the cool charisma required of Sky Masterson. There's no swagger in his step, no mischief in his eyes.

Sharon Kay White brings a refreshing slant to Miss Adelaide, abandoning the usual high-pitched squeak for a full-bodied growl that comes out at the most amusing moments. She's a fine comedian, evident in both phrasing and timing.

Jordan Leigh, so often so good, plays Nathan Detroit as an extended Jewish joke, always on the cusp of squawking, "Waiter! Taste my soup!" He squints and blinks his way through the show but he and Adelaide never establish the true relationship required.

What feels like a thoroughly off-kilter first act finds its feet after intermission. Jimmy Ferraro, breathless during the opening number, raises the roof on Sit Down, You're Rockin' the Boat. The Crap Shooters Dance is an underground wonder, and Montgomery comes into his own on Luck Be a Lady. Move that kind of focus to the first act, and Guys and Dolls could be a winner.
