Enter the Circus by Christina Aguilera... I know I know, she wouldn't have been a first choice for me either, but I found this for our haunt last year and LOVED it. I couldn't believe it was her. It begins... step right up, ladies and gentlemen... and creepy music... wonderful. I thought it made "the clown room" complete. If you would like to hear it, you can find it on YouTube Ahhh, I just listened to it again, I LOVE that song... the intro portion is way creepy
