“My Life Is a Musical,” a musical comedy by Adam Overett, will have its world premiere with a five-week run at the Bay Street Theater in Sag Harbor from Tuesday through Aug. 31.
The play’s protagonist is Parker, a shy accountant with one particular quirk: When he leaves his apartment every morning, he hears people singing and sees them dancing, to the accompaniment of an invisible orchestra. Nobody else knows this is happening. His life is a musical — and he hates musicals.
