Amy Winehouse cut her performance at the Saint Lucia Jazz Festival short after performing only six songs. Winehouse reportedly slumped over a speaker during "You Know That I'm No Good" and struggled throughout the performance to keep time with her band (Check the clips out below). The singer has dealt with a rocky marriage and a well-publicized drug habit. She was recently hospitalized, reportedly due to dehydration and had to cancel her first scheduled comeback gig at this year's Coachella. A spokesman for Winehouse released this statement : Amy would like to express her disappointment that weather forced the abandonment of her show at the St. Lucia Jazz Festival last night. The set started well, but as the heavens opened, a number of technical difficulties occurred on stage, culminating with the lighting rig failing for two songs, in addition, rain began to flood the technical wings at the side of the stage which caused sound problems. Amy and the band tried to soldier on but the set had to be cut short. Winehouse is scheduled to perform again on May 31st in London at a concert honoring her label, Island Records.
