Amy Winehouse has reportedly pledged to give up alcohol and drugs before gigs after forgetting the words to her songs at recent shows.

Amy is currently touring venues in Europe and is said to have made the decision following a number of comments by critics and a talk from her dad Mitch after she was arrested for possession of cannabis in Norway last week.

A source told the Sun: “This tour started pretty much as the last one ended.Berlin was a difficult time for everyone and we thought it was going to turn into another tour full of drunken and missed shows.”

“But she’s now said that she will not drink before her gigs for the rest of the tour.”

“She stuck to it in Amsterdam, amazingly, and gave her best show of the tour yet. Everyone just hopes she keeps it up.”

An organiser of the Amsterdam show added that he was amazed to see Amy sticking to her vow: “She wasn’t drunk when she came in and she did not drink backstage. I don’t think she was stoned either.”

“People were joking about her sober performance. They said, ‘Has the wine bar been closed today?’ But no, she was sober till after her performance. She said she won’t drink before shows any more - only afterwards.”
