When the news broke this week that U2 frontman Bono had to undergo emergency surgery to repair an injury he sustained while rehearsing for the band’s upcoming tour, the chances that more dates would be postponed was clearly on everyone’s mind. Sadly this has been confirmed; the entire 360° North American Tour that U2 planned to start in Salt Lake City has been postponed until 2011. They’ve also had to cancel their first ever performance at Glastonbury.
