“The Roaring 20’s 1999” promises to be really keen with its lively musical, funny, and interactive re-enactment of the highlights of the Jazz Age. Directed by Kate Ramsey, who also co-wrote the show with her husband Greg Ramsey, Joel Kabik, and Gary Mazzu, the show is one of four annual “Theater in the Mansion” productions put on by the Mt. Hope Estate and the acting company of the Pennsylvania Renaissance Faire, which also produces outdoor theme weekends and the summer-long medieval fair.

As a mourner for poor Bugsy Pirandello’s dearly beloved Ma, you’ll start your Roaring 20’s experience by entering the Victorian mansion “funeral parlor,” only to find out Ma’s doing just fine, and you’re in an elaborately decorated “speakeasy,” where you can sample the Estate’s home-brewed “hooch” (offered for medicinal purposes only, of course). While you’re wine tasting, you’ll mix with Bugsy (played by Karl Crose), the gang leader who recently fixed the vote to get elected mayor; Officer Big Mick O’Malley (Stanton Davis), the well-meaning but not too bright cop; silent movie stars Charlie Chaplin (Joel Kabik), Lillian Gish (Diane Neighmond), and John Barrymore (Greg Ramsey); aviatrix Amelia Earhart (Lauren Volkmer); the “lost generation’s” premier novelist F. Scott Fitzgerald and his zany wife, Zelda (David Godbey and Kerri Slavin); and the gangster’s moll, Isadodra Einstein (Vanessa Webb).

Director Ramsey explains “Isadora” is a fictional character based on the real mobster Isador Einstein who ran the Purple Gang in Detroit, but the decision to not use him, was deliberate.

“This was such a violent part of our history, that we wanted to give the flavor of it, without focusing on the real evil some of the people were capable of. We wanted to soften this part of the era, to make it more palatable for families.”

Following the half-hour of conviviality with these bimbos (flapper-speak for great folks), you can choose to attend three of five different shows:

• In the Mansion’s Theater Room, Charlie Chaplin will amaze and delight audiences with his characterization of the star’s performance in his movie “Modern Times,” with audience members invited to participate in the eloquent physical language of the silent movie.

• In the Dining Room, there’ll be a genuine old-time radio show, with John Barrymore and Amelia Earhart performing in the on-going serial “The Race,” featuring audience-produced sound effects.

• F. Scott (“Scotty”) and Zelda Fitzgerald are featured in the Morning Parlor, celebrating the centennial of fellow writer Ernest Hemingway by making a home movie of his novel “The Sun Also Rises,” complete with cast, crew, and extras played by audience members.

•“Dem Wuz Duh Daze” in the Library brings together arch criminal Isadora Einstein and her nemesis, Officer O’Malley, as they musically rehash old crimes and tackle a few new ones. As director Ramsey explains, “This is the show’s history piece, without the muck and gore, but full of music, vaudeville, laughs, and audience participation.”

• The big production number is in the Ballroom, with the spectacular “Chugg-a-Lugg Grubb Clubb Cabaret” featuring Lillian Gish, Bugsy, Ima Starlett (Mia Seitz), and piano player Tickles Ivory (Kate McCutchan), who will be performing such old-time vaudeville favorites as “Yes, Sir, That’s My Baby” and “Hello, My Baby,” with loads of special effects and exuberant dance numbers choreographed by Lindsey Clinton.

At the conclusion of the shows, you’ll wind up either in the Ballroom or the Theatre Room — where a really swell surprise awaits you. We promised not to reveal what happens, but director Ramsey promises you’ll leave the Mansion feeling like the cat’s meow.

“Life is so busy and so fast these days, that we’ve lost our sense of community. What’s great about interactive theater is that by the end of it, everyone knows and relates to each other. I think that’s why people come to see the shows out here, because it’s nice to be involved. It’s nice to play.”
