"I Love You, You're Perfect, Now Change" is an "Our Town" about couples only.

"I Love You, You're Perfect, Now Change" continues weekends through Oct., 12, Pennsylvania Playhouse, Bethlehem.

Not unlike playwright Thornton Wilder's "Our Town," which time travels through decades of life in a small town, playwright Joe DePietro's "I Love You, You're Perfect, Now Change" traverses the bumpy road in the lives of couples.

"I Love You, You're Perfect, Now Change" does it with song (lyrics by DiPietro; music by Jimmy Roberts). Several are quite good, most very funny and some, as with the musical itself, are replete with life lessons.

Unlike "Our Town," in "I Love You, You're Perfect, Now Change," the couples themselves tell their stories in dialogue and song. We, the audience, become the omnipotent narrator, albeit, internally, with the exception of a glance or nudge, as we knowingly relate.

Eight actors play multiple roles. On opening night, Chip Rohrbach, who skillfully and sensitively directs, choreographs and did set design for "I Love You, You're Perfect, Now Change," filled in for Ralph Montesano, who had a sore throat.

The stage setting is minimalist, with a few chairs and tables, a clever-fold out "bed," and office chairs on casters, the latter with actors rolling in unison to replicate a family car trip (celebrated in song with "The Highway Of Life").

A trio of Kevin O'Connell, electric keyboard; Linda Kistler, violin (opening night) and Louis Pettinelli, bass, are on a riser at center stage. Usually, musicians are backstage in Pennsylvania Playhouse productions. The chamber trio on-stage setting works well sound-wise and visually for this production. Lucille DeMasi Kincaid is music director.

Lighting design by Pam and Tom Steigerwalt utilizes spots and enhances the mood of each scene. Costumer Shawn Kerbein helps to keep the numerous characters played by the same actors differentiated.

The musical-comedy is divided into 11 scenes in the first act and nine scenes in the second act, most of which include a song. One song is funnier than the other. There are audience chuckles, out-loud laughter, and even a few tears.

Subject matter includes speed dating, dating sites, in-laws, disparities between men and women and, of course, weddings and marriage. The scenes are true-to-life, but exaggerated.

The songs are a mélange of 1950's through 1980's pop song styles with some nifty rhyme schemes: "My hairline's receding, My ulcer is bleeding."

"Cantata For A First Date," which opens the show and is reprised twice, has excellent ensemble singing, as does the finale, which invokes the play's title.

Each cast member has his or her moments, in solo or duo. Each delineates multiple roles, moving quickly and convincingly from one character to the next.

Beth Linzer has a lovely and flexible voice, as well as a zany comedic sense, that allows her to project several music styles, none more so than the country and western song, "Always A Bridesmaid."

Linzer, Vicki Montesano and Lori Sivick are a hoot in "Single Man Drought." Linzer also scores with Charles Weingold III, in his macho man stance, for "Marriage Tango."

Valynn Turkovich has a beautiful voice, and is able to play against her striking stage presence in her duet with Sebastian Paff, who puts forth a puppy dog stage persona, on "Tear Jerk," which sets forth the difference between "chick flicks" and "action films."

Sivick is a live-wire on stage, especially in "A Stud And A Babe" and "I Will Be Loved Tonight," both with John T. Monahan, who proves versatile and endearing throughout the show.

After all the laughs, and there are many, and all the relationship tips, and there are many, it's the final scene that lifts the play from an also-ran to a near-classic.

Montesano and Rohrbach (subbing for Vicki's real-life husband, Ralph) are at a funeral. With resignation, they sing, "I Can Live With That." It's a poignant conclusion.

If you're a new couple, an about-to-be-couple, or a long-time couple, go see "I Love You, You're Perfect, Now Change." It's couples' therapy, in song, dance and not only for laughs.
