Adam Gwon remembers the moment he saw the landscape that inspired Oscar Hammerstein II’s lyrics, “The cattle are standing like statues” for “Oh, What A Beautiful Morning” in the Rodgers and Hammerstein music, “Oklahoma!”

“They took us on a tour of Oscar Hammerstein’s farm. We saw the porch where he sat and looked out over the field where he wrote ‘There’s a bright golden haze on the meadow,’” recalls Gwon.

Gwon, a Broadway songwriter, visited Hammertein’s farm, now Highland Farm Bed & Breakfast, during the first Bucks County Playhouse Oscar Hammerstein Festival, where he returns April 29 - May 1.

Bucks County was more than OK as a place of inspiration for “Oklahoma!”

Hammerstein (1895-1960), a mentor to Stephen Sondheim, died at his home, Highland Farm, Bucks County. Hammerstein’s masterful use of words in shows like “South Pacific,” “Carousel,” “Show Boat” and “The King and I” created some of the most indelible moments in musical history.

Bucks Playhouse Producers Robyn Goodman, Alexander Fraser, Stephen Kocis and Josh Fiedler have fashioned the Oscar Hammerstein Festival to celebrate the importance of lyrics in the creation of new musicals, with several concerts and workshops on tap.

Gwon (“Ordinary Days,” “String,” “Cake Off”) is part of “New Songwriters Tonight!,” 7:30 p.m. April 29 at Bucks County Playhouse, joined by Broadway singers showcasing new songs, his take on creating musicals and a sneak peek at his upcoming Bucks County Playhouse production.

“Don’t Ever Leave Me: The Love Songs of Oscar Hammerstein II,” 7:30 p.m. April 30 at Bucks, is a benefit concert hosted by Ted Chapin, head of the Rodgers & Hammerstein Organization, and featuring Tony-nominated stars of the Broadway production of “Rodgers + Hammerstein’s Cinderella,” Victoria Clark, Lewis Cleale, Santino Fontana, Laura Osnes and its music director, Andy Einhorn. Sarna Lapine is director.

Workshops, April 30, Lamberville Hall, Lambertville, N.J., include:

“New Works Panel Discussion,” Tony Award-winning Broadway composer-lyricist William Finn (“The 25th Anniversary Putnam County Spelling Bee,” “Falsettos”); Chapin, president, Rodgers & Hammerstein Organization; Bucks Playhouse Producers Goodman and Fraser, and Gwon

“Out of Her Dreams: Agnes de Mille & The Modern American Musical,” Video lecture about de Mille (choreographer, “Oklahoma!,” “Carousel,” “Brigadoon” by choreographer and Steps On Broadway founder Patrice Soriero

“Oscar Hammerstein: His Life and Times,” Hammerstein biographer and Grammy Award-winning record producer Hugh Fordin

For the April 29 “New Songwriters” program, Gwon, piano, is accompanied by singers Kate Weatherhead, Santino Fontana and Jessica Fontana, with songs from his musicals, stand-alones, cabaret songs and collaborations in the 90-minute revue (plus intermission).

“It will be a kind of behind-the-scenes glimpse at not only how songs, but musicals, are put together,” says Gwon, who performs excerpts from his new show, “Cake Off,” which runs Aug. 19 - Sept. 10 at Bucks.

“It is sort of a chamber musical comedy with four actors, inspired by a real event at the Pillsbury Bake-Off,” Gwon says of “Cake Off.”

When the Bake-Off prize was upped to $1 million in 1996, continues Gwon, “Concidentally, or not, all these men entered the competition. Our musical is inspired by and adapted from a 10-minute play written by Sheri Wilner, who collaborated on the book for the musical with Julia Jordan.”

“Cake Off” debuted in fall 2015 at Signature Theater, Arlington, Va. “Because it’s a new work, we’re still in the middle of rewrites,” says Gwon, who’s working on commissioned musicals for the Roundabout Theatre Company, New York City, and South Coast Repertory, Costa Mesa, Calif.

Bucks County Playhouse is a storied location for the Hammerstein Festival. The playhouse, a former grist mill, New Hope Mills, built after the orignal, Hope Mill, burned down in 1790 and from which New Hope derives its name, was purchased during the 1930s by a group that included playwright Moss Hart, who cowrote with George S. Kaufman, “You Can’t Take It with You,” “The Man Who Came to Dinner” and “George Washington Slept Here.” The first show, “Springtime for Henry,” starring Edward Everett Horton, opened July 1, 1939, at Bucks.

Bucks became a summer theater stop on the Straw Hat Circuit and a tryout venue. Neil Simon’s “Barefoot in the Park” premiered at Bucks in 1963, starring Robert Redford and Elizabeth Ashley.

Actors who performed at Bucks include Grace Kelly, in her stage debut, and Dick Van Dyke, Angela Lansbury, Walter Matthau. Helen Hayes, Kitty Carlisle, George S. Kaufman, Bert Lahr, Bernadette Peters, Alan Alda and Liza Minnelli.

“The playhouse has that legendary history of theater people. Back in the day, all these amazing Broadway plays got their start at Bucks County,” says Gwon.

The Oscar Hammerstein Festival continues the Playhouse’s original mission to create “a laboratory to nurture the talents of young playwrights and actors to help keep alive traditions of the American stage.”

Bucks was in continuous operation until December 2010. After its purchase by the Bridge Street Foundation, the nonprofit family foundation of Kevin and Sherri Daugherty, and Broadway producer Jed Bernstein, and extensive renovations, Bucks reopened in 2012.

Since its rebirth, two new plays transferred from the Bucks stage to Broadway: Terrence McNally’s “Mothers and Sons” and “Misery,” starring Bruce Willis and Laurie Metcalfe. Also presented at Bucks: “Vanya and Sonia and Masha and Spike,” starring Marilu Henner and its playwright and Bucks County resident Christopher Durang.

“We remain committed to providing a home for talented writers to create new work, and give them a taste of the welcome retreat that Hammerstein found when he moved from New York to Bucks County in 1940,” says Goodman, Bucks County Playhouse Executive Producer.

“We continue to be inspired by Hammerstein’s blending of dialogue and song in the seminal musicals he created. Almost a century later, they remain essential guideposts in the creation of modern musical theater,” says Fraser.

Gwon says there’s something special about Bucks County Playhouse and the Hammerstein Festival.

“While there are other theaters that have new works programs, there aren’t that many that are inspired by lyrics. ... How things are put together. Usually, that stuff is kept very private. A lot of times, it’s those tiny details and choices which make all the difference.

“It does feel that there’s a kind of special mojo about the place and this particular festival. What I find so moving and that we sometimes forget is “Oklahoma!’ and “Carousel’ just didn’t explode and become classical musicals. They went through drafts and rewrites and readings, similar to the events that are happening at this festival.”
