When the Army outfit comes to save the Christmas season for an Army buddy, they save the Columbia Inn in Pine Tree, Vermont, and the careers of some song and dance folks. Some budding romances keep things warm.

It all works out as Irving Berlin’s “White Christmas,” directed by Parker Ryan and Assistant Director Melissa Miller, takes the stage through Dec. 22, Pennsylvania Playhouse, Bethlehem.

The show’s music and lyrics are by Irving Berlin, with book by David Ives and Paul Blake.

Anthony Hahn. as Army veteran Bob, is great as he leads the cast in this classic Christmas story. He and Army buddies, played by Armand Reiser (Phil) and Sean McFarland (Ralph), are terrific in the opening numbers “Happy Holiday” and “White Christmas.”

Sassy showgirls, played by Mackenzie Lewis (Rita) and Marissa Brewer (Rhoda), bring sparkle to the act.

Youthful talent hits the boards, led by Luci Schneck (Susan, later dubbed “Broadway Sue”), who steals the show in every appearance as the charming granddaughter of Columbia Inn’s owner, General Henry Waverly, played by Mark Boyer.

Boyer is commanding as General Waverly, the four-star war hero who even though retired and running an inn in Vermont still yearns to put his uniform on and get back in the saddle.

Lucy Moore (Betty) and Caitlin McDermott (Judy), as the Haynes Sisters, sing their hearts out while winning the hearts of Bob and Phil for whom they have set their caps. When they do their feather fan dance, those guys don’t stand a chance.

Reiser and McDermott and the chorus sing a lovely number, “The Best Things Happen When You’re Dancing.”

Thomas McElhinny (Mike, Announcer) brings humor, comedic timing, energy and talent to the set.

Nancy Sturm (Martha) is hilarious as she tries to keep the Inn above water even if means keeping the General in the dark about exactly what is going on with the money. Sturm dons a sparkly gown for a sentimental number, “Let Me Sing and I’m Happy.”

Nicole Shelly (Cigarette Girl) provides an eye-catching throwback to the time when glamor girls walked smoke-filled hotel lobbies and casinos selling tobacco and Certs breath mints. She also shows her hoofing skills in the dance ensemble.

Gary Boyer (Zeke, Snoring Man) also brings the laughs with his alternating characters. As Snoring Man, Boyer makes for a perfectly obnoxious seat companion on a crowded train. As Zeke, Boyer he brings a pitch-perfect New England twang and folksiness to his role as the handyman at the Columbia Inn.

Lisa Suppan (Mrs. Snoring Man) is a perfect foil for her husband’s sonorous log-sawing. She does credible extra duty in the Dance Ensemble.

Abby Glidner, Ava Sardi, Johnny Bertone, Mackenzie Lewis, Nicole Shelly, Lisa Suppan and Sara Woodring are credited as comprising the outstanding Dance Ensemble. They and Misha Holt and Keith M. Miller Sr. are credited as the Ensemble.

Brett Oliveira’s set and lighting design seamlessly takes the action from wartime Europe to 1950s-era New York City and to rustic Vermont.

Credit for the complex choreography goes to Choreographer Joanallyn Schubert.

Also of superior quality is the costuming, which is credited to Costumer Todd Burkel and Assistant Costumer Nate C. Kuhns.

Music Director Amanda Haag provides a wonderfully-produced musical worth hearing and seeing. Beautifully done.
