We have talked about the reunion here before, but this weekend magicians Siegfried and Roy made it official!

The former Las Vegas fixtures, whose decade-long residency at the Mirage abruptly ceased four and a half years ago when Roy Horn was mauled by one of their famed white tigers, will return to the stage next year for a one-night engagement benefiting the Lou Ruvo Brain Institute’s Keep Memory Alive foundation.

Roy Horn (63) and Siegfried Fischbacher (68) announced their comeback Saturday at the institute’s 12th annual Alzheimer’s benefit at the MGM Grand Garden. This year, tickets to the charity dinner cost $1,500; the event raised more than $12 million. They will perform NEXT February at a location yet to be confirmed.

Siegfried & Roy’s publicist, Dave Kirvin, said the German-born pair are currently working out the details and he would be “very surprised if animals were not part of the performance.”

Horn lost a lot of blood and eventually underwent surgery to relieve pressure in his brain. It was touch and go for some time before he embarked on the long road to recovery—physical therapy is still on the daily agenda—and, as it turned out, retirement. 

“The stage is my life. It took some adjustment. I was really not ready for it,” Fischbacher told the Las Vegas Review Journal in December. 

But Horn’s recovery “cheers me up,” he said. “All the doctors say what he’s doing now is impossible. I’ve always said, ‘I am the magician and Roy is the magic.’ And Roy shows me every day the magic—the magic of life.”

Horn, who said that he still hangs out with Montecore, his “lifesaver,” would only offer a teaser when asked about the possibility of a return to live performing.

The Lou Ruvo Brain Institute, designed by architect Frank Gehry, is set to open in downtown Las Vegas next year.
