What makes this version unique is Jon Lorenz’s original music. Under the music direction of Anthony Lucca, these jazzy spirits spill out in a multitude of ways: advertising jingles during newly scripted commercial breaks; reworked traditional carols; and original numbers with tight harmonies reminiscent of the Andrews Sisters. Lorenz’s delightful music and lyrics elevate the book magically. So integrated is his 40s-era score into this radio play, it’s easy to forget it was never originally there. In fact, it’s hard now to imagine Miracle without it.
