A small Madonna concert that the pop star said was intended to celebrate France’s tolerance instead tested it, drawing boos and cries of “refund!” when she left the stage after just 45 minutes. The show Thursday, billed as an intimate event at Paris’ noted Olympia club, was streamed live on YouTube. By Friday morning, the channel that showed the event disabled comments and had more than 12,000 dislikes compared with 10,000 likes. An invitation to tweet about the show appeared to backfire when audience members used the suggested hashtag @MDNAParis to complain. Madonna’s press agent, Liz Rosenberg, said in a statement that the star’s occasional club shows in the past “were never more than 45 minutes.” … CNN chief Jim Walton said Friday he is quitting, saying the company needs new leadership at a time its flagship U.S. network is suffering through some of its poorest ratings ever. Walton built the company into a profitable international news organization in his 10 years as president of CNN Worldwide, and said it is on track for record profits this year. But the U.S. network is the most visible part of the business and is now entrenched in third place behind rivals Fox News Channel and MSNBC in prime time. Walton said he’ll continue working until the end of the year during the company’s search for a successor. … Darlene Love, a Rock and Roll Hall of Famer who’s considered one of the best background singers of all time, is recovering from a mild heart attack. Her agent Eric Stevens says the 71-year-old experienced some discomfort prior to a performance over the weekend in Asbury Park, N.J. As the pain grew a day later, Love went to a hospital and was told she suffered a mild heart attack. She has returned home, and her planned concerts will go on. Love lent her voice to several of Phil Spector’s hits in the 1960s, in acts like the Crystals and Bob B. Soxx and the Blue Jeans. Love also has Broadway and film credits.
