After a slew of cancelled dates due to “exhaustion,” soulwoman Amy Winehouse showed up for a charity gig in Cornwall, but her performance was more bemusing than musical. The Sun reports that the tatty singer suddenly left the stage after only two songs, then returned to display some first-rate bizarre behavior – slapping herself in the face, knocking the handmic on her head repeatedly, forgetting lyrics, swearing, and spitting into the audience. Halfway through what would be her last song, she dropped the mic on the floor and walked offstage. Naturally, everyone was surprised (?) and angry and disappointed (they’d paid around $66 for a ticket) and voiced mock concern about Winehouse’s self-destructive bent, but wethinks they got their money’s worth. That was one of those “you-had-to-be-there” performances to tell the grandkids about.
