Jonas Brothers fans in Switzerland will have to wait a little while longer to catch their favorite boy band.  The trio pulled out of a concert in Zurich, Switzerland on Saturday night, after Nick, 17, fell “ill with an upper respiratory infection of the nose and throat.” The Jo Bros announced the cancellation on their Twitter page, writing that Nick was sick and “the doctor has advised that he not speak or sing.”The band noted that this is the “first time that the Jonas Brothers have ever cancelled a show for sickness” and apologized to their fans for the cancellation.  “The band, the management and the promoter apologize that the show must be cancelled on such short notice. We will do everything we can to revisit Zurich in the future and perform for our wonderful fans. Tickets can be refunded as of Monday, 9 November until 31 December 2009 at the presale agency.”.
