More than a consummate performer, Rita Moreno is a force of nature, as she proved again over the weekend at the Napa Valley Opera House.

At age 75, Moreno is still going strong. She can command more attention stretching her legs on a piano than chanteuses half her age. She embodies Broadway’s Golden Age, a time when a performer had to be the complete package. Moreno is certainly that: singer, dancer, actor — she can command an audience with a twitch of her finger. She has won every major show business award: Oscar, Emmy, Tony and Grammy. Throw in a Golden Globe and countless lesser awards ,as well. And she may be working on another Emmy. She co-stars with Jimmy Smits in “Cane,” a new series premiering next week on CBS.

Saturday night her material was as wide-ranging as her talent, with songs from nearly every decade of the last century.

She began with homage to the Great White Way, “Broadway, My Street,” a song from a lesser known 1971 show, “70, Girls, 70.” Her other songs included Irving Berlin’s “I Love a Piano (Maple Leaf Rag)” and “I Found a Million Dollar Baby (In a Five and Ten Cent Store)” from Billy Rose’s 1931 show “Crazy Quilt,” the debut of a young Bing Crosby. She also included numbers from more well-known shows: “But Alive” from 1970’s “Applause” (“I think of Lauren Bacall doing that song with that baritone voice of hers.”), “Don’t Rain On My Parade” from 1964’s “Funny Girl,” and the title song from 1966’s “Cabaret.”

Backed by a trio of superb musicians — percussionist Ted Sommer, who was Sinatra’s longtime drummer, bassist Andrew Higgins and pianist Russell Kassoff — Moreno also did her own arrangements of pop standards including Peggy Lee’s “Fever,” perhaps the highlight of the show. She also gave nods to her Puerto Rican heritage, playing castanets on one number and singing an aguinaldo, a kind of Puerto Rican Christmas carol.

A big part of the delight of her show is the stories she has to tell, not only about Broadway and Hollywood, but about day-to-day life in New York. She could easily win an award as a raconteur. From her story about the Jewish delicatessen with an owner named Jesus, to the one about the woman on the Broadway bus asking the stranger next to her, “Is the noise in my head bothering you?” Moreno made each audience member of the packed house Saturday night feel like her personal friend and confidant.

That’s not to say she can’t play the insider and dish the dirt on celebrities like that “quixotic little pixie,” Andrew Lloyd Webber.

To appreciate what an enduring presence Moreno is, she told about being given a newspaper from the day she was born, Dec. 11, 1931. Among the items contained therein, King Alphonse of Spain abdicated and declared a republic; a quality three-piece suit was selling for $39; a European cruise cost $125,  and admission to a movie — what would become a hobby of the young Moreno — was just two bits.

To anyone who, like this reviewer, remembers what the Napa Valley Opera House was a few short years ago — a brick shell with grass growing in what is now the downstairs café — to hear Moreno walk out on stage and say “I love this little theater” was even more astonishing than all those old prices.

What does Main Street have in common with Broadway? Last weekend it had Rita Moreno. Let’s hope that continues.
