Regarding Rescheduling Performance Dates - Please understand MockingBird has limited options available for performance dates. At any given time there are up to 20 bands running, all of which need performance dates. In addition to our bands, MockingBird is often host to other organizations' events (improv comedy, recitals, performances, etc.). And finally, each performance is reliant on the instructor's availability, the sound engineer's availability, and the store staff availability. Thanks again for your patience and understanding.
