"The show will go on for Michael Jackson’s “This Is It” tour. The announcement was made at a June 26 memorial gathering for Jackson, held by the tour’s cast and crew".
"According to a tour organizer, one performance will now be held in September and will be a replica of what was planned for “This Is It” in London. High-profile singers are expected to perform in place of Jackson. Among them, possibly Madonna, who was expected to appear at one of Jackson’s shows in London. A firm decision has not been made as to where the tribute concert will take place, but it’s likely to be in Los Angeles". (source: MSNBC)
Wouldn't it be cool if Madonna did a complete version of Billie Jean which she mixed with Like A Virgin during her Virging Tour back in 1985?
