CLUE the musical first appeared off-Broadway in 1994. Like, the movie, it was a comedy. Having an interest in the theatre (my major is Film, which owes much to to the stage) I admire they way the musical is presented. The set represents the game board, and the suspects act as peices being manipulated by someone else. The other neat thing about the musical is that, like the game, the ending changes each time it is performed.
An audience participation play, the three murder cards are selected at the beginnning of each show, and the dialogue is altered accordingly (only the actor playing Mr.Boddy knows the results before the end) I believe the show went to London as CLUEDO, but I'm not sure. The musical has an official website where you can buy merchandise, however the CD is currently on backorder. I've been monitoring that site for some time, and still see no signs of the supposed 2nd printing.
