A singer replacement leads to immediate dismissal

The singer Anette Olzon is abruptly replaced at short notice by Elize Ryd and Alissa White-Gluz during a concert in Denver in 2012. Hospitalized after feeling unwell, she publicly criticizes this choice on her blog, believing she was not consulted by her bandmates. The group decides to fire her the very next day and replaces her temporarily with Floor Jansen.
