Who wants to go to a predictable concert where the singer is at her best, sings on key, and sends out love to the audience? Not the folks who go to Amy Winehouse concerts. They're cruisin' for a bruisin', and this otherwise frail looking (and oh, so dainty) chanteuse was happy to oblige. The wacked-out warbler didn't miss a note (well, I mean she was consistent in her missing of notes) as she sucker-punched some fool who was bothering her in the audience. Nelson Mandela might have chosen the wrong person to disinvite to his recent shindig. . .
