The eleventh track from the 2002 Chicago soundtrack is actually a deleted scene from the film which song was indeed added to the soundtrack. The song is performed in a conversation between Mama and Velma, in which they discuss Roxie and how she stole Velma’s plot to win her trial.
The song was quoted by Rob Marshall, (the film’s director), to be his favorite scene between the two as well as in the original stage musical.
