The plot involves two men who are, unbeknownst to them, renting the same room. Since Cox works days and Box works nights, their landlord gets away with double rent. That is, until Cox's boss gives him the day off and they meet.
The show was thoroughly delightful. All three actors (John Perine as Cox, Tom Goode as Bouncer, and Clyde Wright as Box) were clearly having fun and so was everyone in the audience. The musical accompaniment was a simple piano, but that worked fine in the intimate space of the Warehouse Theatre.
People are sometimes dismissive of Sullivan for having written such light musical entertainment. But, frankly, how many other 19th century English composers are remembered at all nowadays?
I'd tell you to go see this production, but today was the final performance. However, I will keep an eye out for future performances by this company.
