LAS VEGAS — Illusionists Siegfried Fischbacher and Roy Horn plan to make a one-night-only comeback next February, performing their signature show at a fundraiser more than five years after a tiger attack ended their long-running production on the Las Vegas Strip.

"Siegfried & Roy" will perform at the Lou Ruvo Brain Institute's Keep Memory Alive fundraiser in Las Vegas at a location yet to be confirmed.

This year, tickets to the charity dinner cost $1,500 and raised more than $12 million.

Publicist Dave Kirvin said the German-born duo was working out plans for the act, and said he would be "very surprised if animals were not part of the performance."

"Siegfried and Roy and white lions and other endangered animals go hand in hand," he said.

The 63-year-old Roy was critically injured when the white tiger, Montecore, sank its teeth into his neck and dragged him offstage in front of a horrified audience at The Mirage in October 2003, ending one of the most successful casino shows in Las Vegas history.

The pair have said they believed that Montecore sensed Horn was having a mini-stroke and was dragging him to safety, rather than attacking him.

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