John & Jen is an intimate and deeply moving musical by Andrew Lippa ( The Addams Family , Big Fish , The Wild Party) that traces the evolving bond between siblings—and later between mother and son—across three decades. Told through a soaring contemporary score that blends pop, folk and musical theatre influences, the story follows Jen as she reflects on her childhood with her younger brother John. Their connection, shaped by youthful rebellion, family expectations and unspoken love, is marked by small but powerful touchstones—including a well-worn baseball glove that becomes a quiet symbol of memory, loss and enduring devotion. As Jen grows into adulthood and raises her own son, the echoes of her past shape her hopes, fears and fierce love as a parent.
