Rocker Brian May revealed that he will never tour in the U.S. again because it’s “too dangerous.”The legendary Queen guitarist told the Daily Mail that while he loves the country, its volatility is making him think twice. “It’s very sad because I feel like Queen grew up in America, and we love it, but it’s not what it was. May, 78, performed in the U.S. with American Idol alum Adam Lambert on an extensive “Queen + Adam Lambert” tour, beginning in 2012. Unless that changes, I won’t do it,” he told the Daily Mail. “I don’t know when Queen will be back on stage, it’s an unknown we’ll take it day by day,” May said.
