Dead Letter Office A crew of kids at the dead letter office must deliver every letter left in the bin before sunrise - including one that was never meant to be sorted at all. The cast will choose the production’s official title during the first rehearsal. Title options may include Dead Letter Office, Undelivered, and Return to Sender. This is an original YTU musical with a run time of approximately 20–30 minutes. TECH REHEARSAL May 18, 4:15 - 6:30 pm May 20, 4:15 - 6:30 pm PERFORMANCES May 21 at 7 pm May 22 at 11 am & 1 pm
