Maybe we shouldn’t be surprised that an annual live music event called Wine, Women and Song, happening Jan. 27-29 at the Kerrytown Concert House, is so popular that a fourth show was recently added. I mean, of those three things, what’s not to love?

Plus, this year marks the 10th anniversary of the show, so several of the classical, jazz and cabaret numbers featured will revisit moments from WWS concerts past.

But the whole idea for WWS came about after several female performers worked together in a stage production of “Follies” at the Michigan Theater.

“It was just this absolutely wonderful experience that bonded us together, and we thought, ‘Why don’t we do something with just women at Concert House?’” said KCH founder and executive director Deanna Relyea, who’s performed in every WWS show so far. “ … We’re all friends, so each time, it’s like going home.”

Over the years, the WWS line-up has changed very little, according to Relyea. This year’s program features approximately 20 numbers performed by 12 vocalists: Sue Booth, Carolyn Burnstein, Wendy Bloom (who also directs the show), Shelley MacMillan, Lisa Gray, Roxy Diederich, Beth Major, Sylvia Pittman, Relyea, Jane Schoonmaker Rodgers, Susan Shipman and Monica Swartout-Bebow.

And did I mention the wine? Complimentary wine, as well as alchol-free options, will be available at each WWS performance.

As to why the annual event has seemingly achieved cult status locally, Relyea said, “There’s a big audience for song and cabaret type of things. People need it - especially in the world today. You go there, and during some of the songs, you'll see tears on the faces of some people in audience, but there’s also lots of laughter. It’s very cathartic. It just gives people therapy.”
