NIGHTWISH cancelled the last four shows of its North American tour — September 23 in Knoxville, Tennessee; September 24 in Charlotte, North Carolina; September 26 in Baltimore, Maryland; and September 27 in New York City — due to Anette Olzon's "sudden severe illness," according to a posting on the band's web site. "This was one of the best tour legs we have ever done, and it's a pity it has to end this way, but there's no competing with the forces of nature," the group said. "There is nothing anybody can do about these things. We want to thank all the fans for all the sympathy, you guys have been so understanding, it's heartwarming. Thank you!"
tal vez eso explique algo :S
