The cast of “The Big Bang Theory” stole the show at the 21st annual A Night at Sardi’s tribute to the Best of Broadway.  Their performance of “Time Warp” produced a standing ovation at the March 20 benefit for the Alzheimer’s Assn.

Those TV thesps, full of energy and dance moves, donned some interesting costumes, especially Jim Parsons, who wore a bustier complete with fishnet and heels on stage at the BevHilton. As the show’s Johnny Galecki put it, “The more you drink, the better I’ll sound.”

Alcohol wasn’t the only thing flowing as Jason Bateman kicked off the night, noting, “We tried to create our own Sardi’s here, as you can tell.  The New York Times theater review wouldn’t be very good.  But hang on, there’s one more joke after dinner.”

Another show-stopping perf came from “Smash’s” Leslie Odom Jr., whose “Jersey Boys” medley hit every one of Frankie Valli’s high notes.

But the night belonged to honoree Brian Grazer, who received the Burrows Entertainment Award from Ron Howard.

“Growing up with Don Knotts, Brian brings back some of those memories,” said Howard. “Especially with his reactions like ‘huh?’ and ‘really?’ Brian’s reactions are indicators of what’s going on in his brain, large amounts of curiosity and creativity.”

Also honored was British actress Jill Gascoine.  The festivities raised over $1.1 million for the Alzheimer’s Assn.
