In her first concert since leaving rehab, Amy Winehouse showed up almost an hour late, appeared distracted and had visible cuts on her arm and a bandage on her hand.

Her performance in front of 90,000 people at Lisbon's Rock in Rio festiva was brief, clocking in at 55 minutes, without an encore. At least she apologized.

"Hey Lisbon," Winehouse told the crowd, which booed when she failed to appear at her advertised time but gave her a warm welcome when she appeared. "I'm sorry I'm late."

The Grammy-winning jazz-pop diva also apologized for a sore throat and her voice cracked during the set.

Wearing a short dress, Winehouse paused to talk to members of her band, fiddled at length with her microphone, sucked on lozenges and at one point dashed offstage but quickly returned. Cuts were visible on her left arm, and her right hand was bandaged.

Winehouse's musical career has flourished despite her erratic behavior, missed concerts and stints in drug rehab. She was the third act of the day on the festival's main stage, coming on before headliner Lenny Kravitz. Her management told the festival organizers she would not speak to the media.
