Anastacia tells Launch.com that she’s been an Elton John fan since she was a child because of his fantastic music and his outrageous eyewear. “I was very influenced, I think, by Elton John and his glasses,” Anastacia said. “I think that he made me feel very comfortable. When in fourth grade I had to get glasses, I didn’t feel like that was a wrong thing–I thought it was pretty cool. I always wanted glasses, so when I had to go get them, I was, like, ‘Oh, yeah! So cool!’ I thought that was the coolest thing in the world, because I was so ready to put them on.” She will hit the stage — along with Elton — since she underwent a form of breast-cancer surgery earlier this month at a post-Oscar party on Sunday (March 23).
