A few concerts have been cancelled for U2 and The Foo Fighters.  The Foo Fighters have rescheduled shows in Edmonton and Calgary after Dave Grohl lost his voice.  Grohl made the best of a bad situation, joking “That’s the last time I ever make out with Bono.”  Bono of U-2 also lost his voice during a performance in Berlin on Saturday, forcing the cancellation of that show after only a few songs.
