Prince announced last week that he'd be heading out on a solo European tour - just him, a piano, and a microphone. Obviously dubbed the Prince Spotlight: Piano & A Microphone tour, he promised it would be "more naked, more pure."

It was set to start on 21st November at Vienna's Konzerthaus, but owing to the terrorist attack in Paris on Friday 13th November the tour has been cancelled until further notice. "Due to the tragic events in Paris, the tour promoter has decided to postpone the upcoming European tour until further notice," said a note on the Konzerthaus site, which Prince linked to in a tweet.

There are as yet no visible plans for rescheduling.
