Illusionists Siegfried and Roy will give their final performance ever tonight at the Keep Memory Alive benefit dinner at the Bellagio. This is the first time in five years that the duo will appear on stage after Roy Horn was attacked by their tiger Montecore back in October 2003. Tonight’s performance is expected to last 15 minutes and no one knows if any of the animals the duo have used in their previous act would make an appearance. Siegfried and Roy’s performance will air March 6 in a one-hour special on ABC’s “20/20.”
