Nightwish Singer Hospitalized

Her place was taken by support band Kamelot's backing singers Elize Ryd and Alissa White-Gluz. Olzon explains: "I got very ill and thought it was a kidney stone. I got worse in the evening and started vomiting heavily. The hospital said I should cancel the show and come straight to the ER. I was there all night and they did blood tests, ultrasounds on my kidneys and finally a CT scan. The tests didn't show why I was so ill, but probably the stomach pain has a connection with me having the flu, or just stress.
