Urs Toni Bühler (born 19 July 1971) is a Swiss classically trained tenor. He is a member of the classical crossover group Il Divo, who have sold over 30 million copies worldwide discs. In December 2003, Bühler became a member of the international musical quartet Il Divo along with Carlos Marín (Spain), Sébastien Izambard (France), and David Miller (United States). He had an informal first audition with the group's creator, Simon Cowell. In Cowell's office, he simply asked Bühler to sing for him unaccompanied. Impressed by Bühler's tenor voice, Cowell offered him a place in Il Divo. Their first album, Il Divo, became a worldwide multi-platinum-selling record when released in November 2004, entering the US Billboard at number four and selling five million copies worldwide in less than a year and knocking Robbie Williams from the number one spot in the charts. Their second album, Ancora, was released in November 2005. Il Divo's third album, Siempre, was released in November 2006. Their fourth album, The Promise, was released in November 2008 and shot straight to number 1 in the UK.
