Madonna’s Nov. 28 concert at London’s Brixton Academy can only accommodate 3,500 audience members and, not surprisingly, those tickets are gone. (The event marks her first live British performance in seven years.) But on Thursday, MSN, which is part of Microsoft Corp, announced that the performance will be broadcast live on the Internet. Reuters reports that the concert could conceivably challenge the world record for a Net audience, a landmark currently held by the three million viewers who logged onto the Webcast of Paul McCartney’s concert at Liverpool’s Cavern last year. The Madonna concert can be accessed on Nov. 28 at http://www.msn.co.uk/madonna. In other news of the Material Mom, 42, The New York Post reports that she is set to shell out $11 million for a six-bedroom townhouse in London’s trendy Notting Hill area. Should the story pan out, it will mark Madonna’s first purchase of a home in the British city, where up until now she has only rented.
