U2 frontman Bono has had emergency spinal surgery after suffering an injury he sustained while preparing for the band’s tour dates.
The 50-year-old musician was treated at a specialist neurosurgery clinic in Munich and is expected to stay there for a number of days.
He will then return to his home in Ireland to recuperate further, a spokesman said.
The band’s next tour date in the US on June 3 has now been postponed, while their appearance at Glastonbury – the world’s largest outdoor music festival – may be in doubt.
Further information about the possible impact Bono’s surgery may have on other tour dates would be announced in due course, a statement on the band’s website added.
The Irish rock band was due to perform a string of gigs across North America, returning to Europe in August.
They were due to begin rehearsals on Tuesday for the opening date in Salt Lake City, and are scheduled to headline the Glastonbury Festival on June 25.
U2 manager Paul McGuinness said of the tour: “We will make plans to reinstate the dates as soon as possible.”
He added it was “unfortunate that we’re inconveniencing fans” and that it was causing disruption to the band’s 400-strong crew.
He advised fans to continue monitoring the U2 website for further news.
The 360 Degree tour earned the band around $109 million in 2009, making it the world’s most profitable tour of the year, according to figures from Billboard magazine.View Comments
