Another way to promote world peace: let people visit the U.S. unless there's a clear and compelling reason not to. From a press release:
American Symphony Orchestra Replaces Tenor for Season-Opening Concert on Wednesday, October 14 Because of Visa Snafu
Richard Crawley Will Now Sing Title Role in Opera-in-Concert Performance of D’Indy’s Fervaal at Avery Fisher Hall
Dwayne Jones, a noted Australian singer who resides in London, was unable to resolve a visa and passport snafu and consequently could not get clearance to travel to the United States in time for rehearsals with the American Symphony Orchestra. As a result, the tenor Richard Crawley has been brought in by the ASO to sing the title role in the orchestra’s season-opening opera-in-concert performance of D’Indy’s Fervaal at Lincoln Center. The performance will take place at Avery Fisher Hall on Wednesday, October 14 at 8 PM.
Jones becomes one of an increasing number of artists and performers who have been denied entry to the United States for reasons that are unclear.
