Barry Hatton of the AP reports that Amy Winehouse showed up late for her first concert since leaving rehab, giving an underwhelming performance in front of 90,000 people Friday at a Lisbon music festival. The Grammy-winning jazz-pop diva turned up almost an hour late for the outdoor show. She apologized for having a sore throat, and her voice cracked during the 55-minute set. Winehouse, wearing a short dress, appeared distracted during her performance. She paused to talk to members of her band, fiddled at length with her microphone, sucked throat candy and at one point dashed offstage but quickly returned. She had cuts on her left arm, and her right hand was bandaged. Keep Amy in your prayers.
