Donny and Marie Osmond hit the stage at the Pantages Theatre in a cloud of nearly palpable pizazz.
For two hours the indefatigable showbiz veterans, kicking off "A Donny and Marie Christmas in Los Angeles," sang, danced and smiled — oh, did they smile — with a weapons-grade enthusiasm that belied their seen-it-all experience.
At one point on opening night Tuesday, a visibly sweat-streaked Donny, 54, blazed through a rat-a-tat mash-up of the Rolling Stones' "Start Me Up," "Dynamite" by Taio Cruz and, just for good measure, a line or two from the Korean pop smash "Gangnam Style."
Marie, 53, tackled "Climb Ev'ry Mountain" from "The Sound of Music."
The people in the crowd — many there as fans, some no doubt digging for kitsch — cheered the siblings with equivalent force.
If Donny & Marie came to fame preaching the gospel of musical diversity — think "I'm a Little Bit Country, I'm a Little Bit Rock and Roll" — their belief in that approach is equally firm today. Even their so-called Christmas show ventures well beyond sleigh bells and mistletoe.
"We decided it couldn't be wall-to-wall Christmas music," an exceptionally trim and dapper Donny had explained earlier. "You'd have to leave with an insulin shot."
That mix-and-match sensibility — and a deeply committed professionalism, no matter how iffy the material — help explain why Donny & Marie can still attract an audience a half-century into their respective careers.
"Christmas in Los Angeles" runs through Dec. 23, and robust ticket sales are testament to a wholesome allure that's faded little since Nixon was in office.
The duo's cover-every-corner approach — albums, a weekly TV show, "Dancing With the Stars," even Marie's deal with Nutrisystem — almost makes you wonder if the Osmonds were ahead of their time. Or at least if the rest of the entertainment world has finally caught up with them.
"Thank you for the compliment," Donny said with a grin when presented with the possibility that he and his sister were ahead of the curve. "They're not just doing pop songs [on those shows] — they're doing all kinds of stuff," he went on. "So, really, it's variety again. It's giving you the whole pie instead of just one piece."
"It's not easy to do all these styles: country, rock, jazz, Broadway, opera," said Marie, who with Donny brought an earlier version of the Christmas show to Broadway in 2010. "But we've both spent a lot of time working on it. And that's what defines longevity, if you can do it all. I think entertainers see that nowadays."
Beyond the sparkly stage act — one they insist they're constantly improving — "doing it all" today means enduring the sort of full-court media blitz usually reserved for up-and-comers.
On a recent afternoon Donny & Marie cycled through back-to-back interviews in Hollywood, each sibling's perfectly white teeth nearly outshining the sun beaming through a hotel window.
Yet with the clock ticking ever forward, the stars' handlers began glancing at their watches: Donny & Marie were due onstage at 7:30 that evening — and not at the Pantages, but in Las Vegas, where they've been playing the Flamingo Showroom on a near-nightly basis since 2008.
"You want to know something even crazier?" Donny asked, leaning into a reporter more closely than might've been expected. "Last week we were in London."
"For one day!" Marie added, leaning a bit herself.
