The play is called "The Compleat Wrks of Wllm Shkspr (abridged)". They take abridged seriously as they did all of the comedies in one sequence. The whole play is performed by three men and one woman who are kept *very* busy.
The entire second act is devoted to Hamlet and is a good bit funnier than the Harold H. Hecubah version, although it's *not* a musical.
