Following the distressingly incoherent and erratic performance given by Amy Winehouse in Belgrade on Saturday [highlighted to the world through videos such as these of her in a concerning state], it has been announced that a number of gigs have been cut from Amy’s European tour, which kicked off that night.

The troubled singer’s scheduled shows in Istanbul and Athens have been cancelled on Monday and Wednesday respectively this week.

Her disastrous Serbian show has been described by Serbian media as a “scandal,” a “disaster” and “the worst in the history of Belgrade.”

Her representatives said it would be “worked out as soon as possible” whether she would attend the rest of her European tour. The next scheduled concert date after Athens is July 8 in Bilbao, Spain. The tour was to end in Bucharest, Romania, on Aug. 15.

Winehouse would like to say sorry to fans expecting to see her in Turkey and Greece, but “feels that this is the right thing to do,” the statement said. “Despite feeling sure that she wanted to fulfill these commitments, she has agreed with management that she cannot perform to the best of her ability and will return home,” it added. There was no further explanation for exactly why Winehouse was canceling. –Associated Press, via Billboard
