As previously reported by Las Vegas Backstage Access, Garth Brooks poo-pooed any plans he had of performing in Las Vegas, supposedly working out a deal with Steve Wynn. Was it a smokescreen? 
On Monday at the Wynn Encore he had a surprise concert for 600 to 800 VIP guests. The guests arrived at the theater to find black hats on their seats. Out came Brooks, who put on a full concert without a band behind him.
Some say that Brooks already has a Encore contract in his hands, but the sticking point is ticket prices. Brooks, like Bruce Springsteen before him, apparently isn’t comfortable with “Vegas” ticket pricing- at least not yet.
