Fellow Don't Stop Believing judge Chucky Klapow was interviewed and mentioned Anastacia in one of his answers...
Do you know much about your fellow judges?"Well I worked with a pop group in Sweden in 2001, 2002, and around that time I became really familiar with Duncan. I know all about him and have a couple of his CDs. Anastacia is on my iPod! These people were in the forefront of music when I was working with my pop group. I was just thinking about it, I actually think Anastacia may have shared a stage with me at some music awards ceremony back then. I'm a big fan of all of them, so it's an added bonus of the show to get to work alongside these people who I listen to and respect."
