The brother-sister duo, who starred in the "Donny & Marie" variety show in 1976, will play Tuesday-Saturday shows for 26 weeks spread over eight months at the Flamingo Showroom, a hotel official said Friday.
The 90-minute show, beginning Sept. 9, will be presented by Danny Gans and Chip Lightman of GansLight Entertainment. It is being billed as a greatest-hits multimedia spectacle on a custom stage with multiple video screens and a cast of dancers.
"My version of a variety show has been what Vegas has known thus far," said Gans, an impressionist and comedian who has long played in Las Vegas. "What we have now is a true variety show which conveys the real essence of America and the country's love of homegrown talent."
Tickets, which are priced at $85, $99 and $115, go on sale Monday.
In the 1970s, Donny and Marie's musical family, The Osmonds, shared the marquee at the old International hotel with Elvis Presley. The International is now the Las Vegas Hilton."Donny and Marie are timeless entertainers and cultural icons," said Don Marrandino, president of Flamingo Las Vegas.
