Amy Winehouse turned on fans at her concert last night after they started booing her. The troubled star had spent the morning visiting her junkie husband Blake Fielder-Civil in prison - and was obviously unable to handle the strain of the concert, which took place at the Birmingham's National Indoor Arena, and was the first night of Wino's 17-date UK tour. According to fan reports, the singer appeared drunk as she took the stage, had to be supported by her band as she almost collapsed in tears and continuously paid tribute to Blake.

The crowd was not impressed with her antics and began booing with some even storming out in protest. To which Amy responded with insults and an overall out of control attitude. "Let me tell you something. First of all, if you're booing you're a mug for buying a ticket. Second to all the people booing - just wait 'til my husband gets out". Yes, we're all really frightened now.

Amy also changed the words to her songs to make reference to Blake. During "Back To Black" she added the word "Blakey" and at the end of the track she slurred: "Nothing's going to bring my husband back". Before she got to the end of her closing song, her cover of The Zutons' hit "Valerie", she stopped singing, dropped the microphone and walked off stage.

Fan James Dyas, who was present at the concert, stated that "she came on stage half an hour late. She managed four songs but was slurring her words and swaying all over the place. She fell into the guitar stand and dropped the microphone - it was atrocious. The song she dedicated to her husband was so bad it was like swinging a cat round your head." Friends of Amy are worried for her mental health ever since Blake was arrested last week after he was accused of beating up a bartender and then attempting to pervert the course of justice.

Critics' reviews ranged from scathing to sympathetic. The Telegraph noted: "Valerie is a slurred blur and she wrecks Sam Cooke's Cupid by yelling off key". Another critic, who praised the singer's "real emotional honesty", concluded: "When it comes to frankness, and unpredictable emotional whack, I doubt Winehouse knows how to disappoint". The Times described the show as "sloppy" but added: "Clearly the troubled chanteuse has other things on her mind."

Amy's spokesperson said: "It's been a really emotional time for Amy but she was determined to do the gig. She broke down on stage a couple of times with real tears. That real emotion is why people love her, but it's just really heightened at the moment".
