Nightwing
Although Nightwing is commonly associated with Batman, the title and concept have origins in classic Superman stories. The original Nightwing in DC Comics was an identity assumed by alien superhero Superman when stranded on the Kryptonian city of Kandor with his pal Jimmy Olsen. Drawing inspiration from Batman and Robin, the two protect Kandor as the superheroes Nightwing and Flamebird. Following the Crisis on Infinite Earths continuity reboot in 1985, Nightwing was re-imagined as a legendary vigilante from Krypton whose story inspires Dick Grayson's choice of name when he leaves behind his Robin identity.
Anette Olzon
Olzon officially joined Nightwish as their new lead singer in early 2007, chosen from about 2,000 applicants of which 10 made it to prove their place in front of the band. The song on her demo tape was the 2002 single "Ever Dream". She replaced the previous singer Tarja Turunen, who was fired in an open letter in the autumn of 2005. Olzon's demo was one of the first that Nightwish received, although she was originally denied the position, as band leader Tuomas Holopainen was concerned about the fact that she had a young son. However, Olzon was persistent and sent the band a live DVD of her performing with Alyson Avenue. She was then contacted by Nightwish's manager Ewo Pohjola, which eventually led to her taking up the position in February 2007. Tuomas commented on her selection saying "we (the band) took a formal vote, but it was unanimous that she would be the one. It was a matter of heart. We felt she was right." Her identity was kept secret by various methods, including pretending to be Ewo's "Swedish cousin" at a Tarot concert, until she was eventually announced as the new Nightwish singer on 24 May 2007.
