Just as U2 were preparing to embark on another multi-date 360 tour and claim their headlining spot at Glastonbury, it seems that all dates have a possibility of being postponed or canceled. A statement was just posted on the U2 website stating that the singer has “undergone emergency back surgery for an injury sustained during tour preparation training.” The message goes on to say that an announcement will soon be made regarding future dates. As of now, the first date of the tour in Salt Late City has been postponed.
