The CD on the other hand is diificult to obtain.   It's out of print but you can occasionally find it on Ebay.    There are two versions of the CD.   The one with all of the possible endings with 28 tracks is the one that is most desirable and the one you would most likely want.  But be prepared to pay upwards of $ 50 for it.   There is another version that is the exact same cast recording but does not have all of the possible endings and only has 21 tracks.    Did a quick search on Amazon and there are used ones for about $87 and up.  Not sure if they're the full 28 track version.

 

Hope this helps and good luck if you're planning on doing the show.   Alot fun if done well.
