David Bowie has been forced to cancel all his live dates in July, including his sets at the Oxegen, Roskilde and T in the Park festivals, because of that trapped nerve in his shoulder.

As previously reported, the injury first caused Bowie real problems when he
had to cut short a concert in Prague last week after his shoulder pain
became unbearable. It was hoped with some rest he could continue with his
European tour, but after his set at the German Hurricane Festival he was
admitted to hospital and a handful of European dates due to take place this
week were postponed...
