I want to know the answer to the following question:
In what month was Perfect Harmony's Off-Brodway debut?
All the background I'm provided with is that "The a cappella musical Perfect Harmony, a comedy about two high school a cappella groups vying to win the National championship, made its Off Broadway debut at Theatre Row’s Acorn Theatre on 42nd Street in New York City in October, 2010 after a successful out-of-town run at the Stoneham Theatre, in Stoneham, Massachusetts.". Is that enough to answer the question?
Answer: yes
