Support wasn't strong enough apparently. Oh, that's Celine Dion by the way - she cancelled a concert scheduled for Aug. next year. Media personnel are to blame - according to Dion's husband and manager, Rene Angelil - radio and newspapers comments continually insulted her. Angelil quoted specific reporters. One, David Rodeniser, said, "Oh, no. Say it ain't so. Celine Dion is our big Concert on the Common news? What could be more of a letdown?" Rodeniser responded by pointing out positive things he also mentioned in his comments. (see CTV story and reader comments here)
CD apparently performed there four previous times, so perhaps the "Dions" are a bit touchy this time. Otherwise, it could cost the city of Halifax a couple of million dollars in revenue. It didn't help that negative comments about her were given public space, but, that's freedom of the press, and it would be much worse to cancel that.
