The credits list none of the songs in the movie. At all.
After Virgil kills everyone and the dolls escape with the rockers, the screen blacks for the credits, but instead Virgil's assistant walks out and explains that there is an alternate ending that some may find more suitable. The last five minutes of the movie play over, except now the rockers throw the dwarf across the room before the wedding, and are forced to play the wedding march for Virgil. In this version of the ending, however, Virgil's new wife reacts positively to him. The rockers start to play music, which continues over the end credits.
