so many requests from people wanting to use our tracks but we normally say 'no'. This is only the second time we have given permission. We said 'yes' this time because we admire Madonna so much and always have done. She has got guts and has been around for 21 years. That is not bad going." The song premiered in September 2005, during a television advertisement for Motorola's ROKR mobile phone. The advertisement featured Madonna and other artists jammed in a phone booth.
