Included is an In-Depth 20 page booklet with pictures of the actors and descriptions of the song environments. I will not argue the virtues of the original play vs. the movie as I grew up on the movie. However I have seen a local version of the play. This recording gives you the feel that you are there. Many people appreciate the added songs because they paint a more in-depth story especially the added tracts. However I just like the music for its own sake. I am not going to go through the list of songs or singers as I thing you will enjoy discovering them your self. All I can say id even if you have other versions of the score you need to add this to your repertoire.
