Here's a great Disney villain rendition of the "Cell Block Tango" number from Chicago. It was done by a talented group of people gathered together by American Idol finalist Todrick Hall. It also stars fellow Idol alums Pia Toscano and Adam Lambert, as well as Broadway star Shoshana Bean, Make it or Break It's Cassie Scerbo, Glee's Amber Riley, So You Think You Can Dance's Blake McGrath, and singer Kimberly Cole. They take on the roles of The Little Mermaid's Ursula, 101 Dalmatians' Cruella De Vil, Snow White's Evil Queen, Sleeping Beauty's Maleficent, Alice in Wonderland's Queen of Hearts, and The Lion King's Scar.
The video was made in the spirit of Halloween, and I've included the original version of "Cell Block Tango" below for comparison.
