According to this article in the Surrey Advertiser on-line, the 2009 concert has been abandoned owing to the lack of sponsorship (though whether because the 2009 Derby itself still lacks a sponsor, or because sponsorship for the concert could not be obtained, is unclear).
The article quotes Cllr Jean Smith, chair of Epsom and Walton Downs Conservators, saying: “I think this is very disappointing news.” I’m not so sure. See the post on the 2009 Concerts below for a different point of view.
