Amy Winehouse has vowed to stay sober on stage for the rest of her European tour, after a disastrous debut.
The Rehab singer - who cancelled several dates when she was hospitalised in August after a drugs overdose - pledged not to drink before going on stage after the run of shows got off to a disastrous start on the opening night.
At last week's Berlin concert Amy forgot the lyrics to some of her songs and stumbled on stage. She was then arrested for possession of cannabis in Norway.
