Within the level entitled "The Murder of Crows", you will notice that there are three seperate bars in the area: Salsa, Rock and Blues. You can acquire outfits that correspond with the particular bars. Once you have selected the appropriate costume for your bar of choice, enter the bar, position 47 to stand amongst the other dancers on the dance floor and then leave the controller alone. After a few minutes 47 will start to get his groove on with the ladies and start dancing.
