Amy Winehouse may have been one of the most sensational live acts ever but her substance abuse demons were never far away. At a concert in Belgrade in 2011 she was booed by a 20'000 strong crowd who had bought tickets to hear her perform. Unfortunately Amy appeared too drunk to perform and stumbled about the stage to the distress of the crowd. Subsequent planned tour dates were canceled when Amy's troubling performance became international news.
