There are few finer examples of of why a performer should be sober when they go onstage than this video of Amy Winehouse performing in Belgrade on the 18th of June. This is a comeback of sorts, since Amy has been reportedly in and out of rehabs for quite some time now.
And, after viewing the video, I can't see anything clean going on there. Certainly not Amy, nor that nasty weave she is sportin'. So disappointing, a complete waste of a talent.
