Mariah Carey's weekend outdoor concert in Hong Kong was cancelled today due to poor ticket sales and what promoters called "unreasonable demands" from the singer. Carey was scheduled to perform near the city's financial district on Saturday, but concert promoters had only sold 4,000 tickets as of today, despite having heavily advertised the event. "We have decided to cancel the event effective immediately due to both the poor response of public ticket sales and also due to specific last-minute demands which we find wholly unreasonable and not with the best interests of Hong Kong, us and also the fans," the promoters said in a statement posted on their website.
