Donny & Marie, the Las Vegas Strip’s favorite (and possibly only) brother-sister headlining duo, have extended their residency at Flamingo Las Vegas through 2013. Their 2013 run begins with dates starting Feb. 12.

The Donny & Marie show was recently voted the “Best Show” in Las Vegas by the readers of the Las Vegas Review-Journal.

The Review-Journal’s readers also bestowed kudos for “Best All-Around Performers,” “Best Singer,” and “Best Dental Care,” although we may have made that last one up.

The Donny & Marie show at Flamingo began as a limited, six-week engagement back in 2008. Hey, it’s like this blog always says, once you come to Vegas, why would you ever want to leave?

At their fast-paced show, fans are treated to a slew of Donny & Marie hits covering five decades, including “Puppy Love,” “Paper Roses,” “Morning Side of the Mountain,” “I’m Leavin’ it (All) Up To You” and “Soldier of Love.”

Personally, this blog loves the show as much for sibling rivalry barbs as the singing and dancing.

Donny & Marie perform at 7:30 p.m., Tuesday through Saturday (although not, you know, continuously, because that would be weird) in the Flamingo Showroom. Find out more.
