Mabel’s Last Performance is a beautiful example of how the many elements of a production can come together to produce an outstanding whole. The set design, music, acting, and locale seem guided by some omniscience towards cohesiveness. It’s probably a testament to the skill of everyone involved in the production, which contains no drought of big names. Kathi Langston brings a wealth of experience and prowess to the part of Mabel (the only acted part). The show also features music by Ian Tamblyn, a name that should be familiar to many who follow theatre in the capital.
