REHOBOTH BEACH, Del. — Miss Richfield 1981, the longtime drag star known for Provincetown residencies and performances aboard gay cruises, debuted a new show here Monday for an invitation-only audience at the Blue Moon.

The show, dubbed “40 Years on the Throne,” celebrates Richfield’s four decades entertaining largely LGBTQ audiences with tales from her hometown “where butter is a spice and gravy is a beverage.”

Coincidentally, the Blue Moon is also celebrating 40 years in business this year.

Russ King, a Minnesota native, created the Miss Richfield persona to chronicle “her lifelong goal of being crowned beauty queen of her first-ring suburb of Minneapolis.”

Monday’s show — a dress rehearsal before it heads to Provincetown — got off to an unintentionally hilarious start, when Richfield tripped and fell onto the stage. She laughed it off, blaming a nearby female patron for “pushing me.” Then Richfield left the stage and started over.

The riotous show included a rendition of Dolly Parton’s “9 to 5” that brought the audience up to date on Richfield’s recent travels; a video montage of her many outrageous TV appearances, including on “Cake Boss”; and a beauty pageant quiz show with two audience members. Longtime fans will be relieved to know that the new show includes Richfield playing the saw.

At the end of the show, Richfield solicited audience feedback as she refines it for her summer residency. Richfield is scheduled to open the show on May 29 at the Pilgrim House in Provincetown, Mass., and it’s slated to run through the summer, wrapping on Sept. 18. (Tickets are $30 for general admission and $40 for VIP at pilgrimhouseptown.com.)

King now lives in Rehoboth and is planning to return for a one-night-only performance of “40 Years on the Throne” on June 21 at the Blue Moon. (Visit BlueMoonRehoboth.com for tickets, $40.)

The Blue Moon has a full summer of entertainment planned, including performances by the Boy Band Project (June 7, July 19, and Aug. 30); Lady Bunny (July 5, Aug. 23); and Sherry Vine (Aug. 16). The talented Nate Buccieri returns for another summer on the piano, Sundays through Thursdays, 6-8:30 p.m. The award-winning “Climax! With Magnolia” continues on Sundays at 9:30 p.m.
