Legendary brother-and-sister singing duo Donny and Marie have been entertaining audiences for years, and 2018 marks exactly one decade performing their hit show, Donny & Marie, at Flamingo Las Vegas.

What started as a six-week gig in September 2008 has turned into one of the most sought-after productions in Vegas. Together, the brother-and-sister duo has performed more than 1,500 times on the Flamingo stage.

The pair, who began singing publicly as children, perform hits such as “I’m Leaving It (All) Up to You,” “Paper Roses,” “Soldier of Love,” “Morning Side of the Mountain,” and “Puppy Love.” The siblings have been performing together for more than 40 years, starting with a variety show in the late ‘70s. Donny and Marie also perform hits from their solo careers as well as songs from the legendary performers. In fact, you just might here a song or two from such artists as Beastie Boys, Aerosmith and the Osmond Brothers.

"We're headed into our 10th year," Donny Osmond said in a news release. "Marie and I are constantly changing our show. That's probably why we're fortunate enough to enjoy such longevity."

In addition to the music the show dazzles with special effects, videos, dancers and more. No matter what your age, you will have a good time watching these two sing together onstage. The show has been voted "The Best Show in Las Vegas" by the readers of the Las Vegas Review Journal 2012. They also won the title of "Best All-Around Performer," and Donny Osmond took home the "Best Singer" category.

Donny & Marie perform their hit show select dates Tuesday through Saturday at 7:30 p.m. at Flamingo Las Vegas. The pair is currently performing at Flamingo now through November. You can find discounted tickets here on Best of Vegas.
