Winehouse concert a 'disaster' in Serbia

British singer Amy Winehouse is canceling part of her European tour, her representatives said Sunday, after the singer was booed for being late and stumbling onto stage during a concert in Serbia.

Winehouse will be canceling appearances in Istanbul on Monday and in Athens on Wednesday, according to a statement from publicity company Outside Organization.

The Serbia concert late Saturday kicked off a 12-date tour of Europe. Her representatives said it would be "worked out as soon as possible" whether she would attend the rest of her European tour. The next date after Istanbul and Athens is July 8 in Bilbao, Spain.

The singer would like to say sorry to fans expecting to see her in Turkey and Greece, but "feels that this is the right thing to do," the statement said. "Despite feeling sure that she wanted to fulfill these commitments, she has agreed with management that she cannot perform to the best of her ability and will return home," it added.

Winehouse, who has publicly struggled with drugs and alcohol, was jeered as she performed in Serbia's capital, Belgrade. She stumbled onto the stage, mumbled through her songs and sometimes wandered off. Serbian media described the concert before about 20,000 fans as a "scandal" and a "disaster." The Blic daily said the concert was "the worst in the history of Belgrade."

Clemons remembered at Stone PonyScores of fans gathered Sunday at a legendary rock club to mourn the death and celebrate the life and music of saxophonist Clarence Clemons. The Stone Pony in Asbury Park, N.J., was the place where Clemons, Bruce Springsteen and other E Street band mates got their musical starts. It opened its doors to a small crowd, many adorned in Springsteen T-shirts. A makeshift memorial was created at the club late Saturday as word spread of Clemons' death in Florida from complications of a stroke he had suffered about a week earlier. Fans were lining up to snap pictures and leave flowers to honor Clemons. He was known as the Big Man, a nod to his physical size, stage presence and booming sax notes. Gary Mottola, who owns the Stone Pony, said that the E Street Band was "the soul of Asbury Park" and that Clemons was the soul of the band.
