The estrogen level of “Girls Night: The Musical” did everything it could to blow the roof off of the palatial Hanover Theatre Wednesday night. Louise Roche’s funny and touching celebration of indomitable female friendship is part anthem, part confessional and all party.

It’s one big, R-rated bachelorette party for women of all ages at Stoneham Theatre’s bawdy, raunchy musical, “Girls Night: The Musical,” that swept the British Isles since 2003, and has North Shore women dancing in the aisles, singing anthemic women’s songs with gusto. The play has toured the US since May 2007.

"Girls Night," a popular revue about five middle-aged women who sing out their troubles in a wild night at a karaoke bar, was blessed with one of those fortuitous beginnings that makes you a believer in the "let's put on a show" approach to theater.

The Setup: When a show is semi-scripted, with ample audience participation, a lot depends on the stage presence of the m/c, and Easter Catechism is fortunate indeed to have Denise Fennell filling that role.

Last night was press night at the Gem Theatre, where the newest version of comedy catechism was a smashing success; Nonie Breen, the actress playing the part of Sister, had the audience in fits of laughter within five minutes, to the point it made some people cry.

Rochester’s biggest party of the summer will continue through the 13th of August. Due to popular demand, Geva Theatre Center announces ten additional performances of Girls Night The Musical.

But the less-than-traditional audience that filled the theater was merely a reflection of the show on stage. As the name suggests, "Girls Night" is definitely one for the ladies, although there were a handful of brave men in the crowd on opening night. ("Suckers!" the welcoming voice-over playfully taunted.) On the surface "Girls Night" appears to be a glorified bachelorette party onstage, but at its core, the show is a relatively rousing two-hour celebration of girl power.

Call your girlfriends and head to Geva Theatre – It's "Girl's Night Out". That's right. Girls Night: The Musical is now on stage and the party starts the minute the lights come up on stage. The show will have you dancing in your seat.

As we are currently experiencing a heatwave in Rochester, I thought it only apropos to talk about the heatwave happening in our Mainstage, namely Girls Night the Musical. Think of it as “Sex in the City” meets “Desperate Housewives” with a little Mamma Mia thrown in for good measure.

BOTTOM LINE: Our highest recommendation! I’ve never seen an audience enjoy a musical more than at this touching and hilarious romp.

"Tim Flaherty, the president of Entertainment Events Inc., and Louise Roche, a British playwright, have discovered a theatrical goldmine."

From The Philadelphia Inquirer, By Toby Zinman: The "girls" who came to see Girls Night were every age, shape, size, race, and color. There were even a few guys. A group of 11 high school teachers was sitting next to me. Everybody seemed to have the same good time. The show's unpretentious fun and the talented, unembarrassable women on stage had all of the audience on their feet, clapping, singing, and dancing in the aisles.

SPECIAL TO THE REGISTER The cast of “Girls Night: The Musical” tell the story of five longtime friends, one of whom is a ghost, and belt out 14 classic songs. (Special to the Register)

The line on the accompanying pop-out box says “Play review,” but “’Til Death Do Us Part: Late Nite Catechism 3” is more an event. The audience is the show.
