As previously reported, on Friday, September 28th, 2012 Nightwish took the stage at the Ogden Theatre in Denver, CO without Olzon, who was hospitalized due to illness. Support act KAMELOT's backing vocalists Elize Ryd (AMARANTHE) and Alissa White-Gluz (THE AGONIST) stepped in to fill Olzon's role alongside bassist/male singer Marco Hietala.
Olzon released a statement (found below) explaining the situation, and followed it up the following day with her take on having Elize and Alissa stepping in for her. A couple days later she was officially given the boot and replaced by REVAMP singer Floor Jansen, who completed the tour.
"I am so sorry that I couldn't be on stage yesterday in Denver. I got very ill the night before and first went to the ER in the morning and was there for five hours before they released me with some painkillers and thought it was a kidney stone. Unfortunately I got worse at 7PM in the evening and started vomiting heavily and my fever rose. After talking to the hospital they said I should cancel the show and come straight back in to the ER. I was there all night and I was very dehydrated so they gave me two litres of fluid though an IV, they did blood tests, ultrasounds on my kidneys and finally a CT scan. These 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. They did find something else though and for that I'm grateful. If I didn't do the scan I wouldn't know there's a big cyst in my liver and I need to go check it out ASAP at home. I do feel better today but still fever cough and a very sore throat but hopefully I can be on stage tonight, even if it means shorten the set list. Thanks for your time to read this! Enjoy this day!”
Olzon's additional post:
"And one more thing.... I was never asked if it was okay they used Elize and Alissa in the show last night. I don't think it's a good decision they made and I'm sorry for those of you who came to see the whole band but got something else. But I was very ill and this decision wasn't mine. Tonight I'll be on stage doing my best despite illness :-)
Thanks for your support! And you know, this is just music. Like life, sometimes we get ill and shows do get cancelled. Rihanna wouldn't ask Britney Spears to sing for her if she was ill. To think a show is more important than the humans in the band is for me, so totally not in this world."
