Siegfried and Roy were a legendary entertainment duo who for a long time were the highest-paid act in Las Vegas.
From 1990 to 2003 they wowed audiences at the Mirage Resort with their flamboyant mix of magic - involving white lions and tigers.
That all famously ended in 2003 when Roy Horn was attacked on stage by one of their tigers.
New Zealand composer and lyricist Luke Di Somma has written their story as a stage show Siegfried & Roy: The Unauthorised Opera, which was a hit at the recent Sydney Festival.
He's also written the original music for a new musical comedy TV series called Happiness - starting Rebecca Gibney, which has just begun filming, an a concert of his work is currently on as part of the Hamilton Arts Festival.
