3. Siegfried and Roy
Another great addition to the list of all-time greatest headliner shows in Las Vegas is Siegfried & Roy. The duo is a pair of magicians who became famous for their animal act at the Tropicana, which dazzled tourists. They began performing in 1973. In 1989 when Steve Wynn built the Mirage, the duo was given a chance to showcase their act featuring white lions, white tigers,waterfalls, lagoons, and tropical foliage. At the Mirage Resort, they performed in 5,750 events in a span of 13 years. They made some of the best shows in history, while at the same time raising awareness for animal welfare.
