“David Lindsay-Abaire is a much-admired young playwright whose credentials include two years at the Juilliard Playwrights Program and an early stint staging absurdist dramas in the East Village and SoHo. His big career break came five years ago when Ben Brantley, the chief theater critic for The New York Times, raved over the Manhattan Theater Club production of his quirky dark comedy ‘Fuddy Meers.” Now, Lindsay-Abaire has improbably emerged as Broadway’s best hope of reviving the musical with his acerbic wit, willingness to push an audience’s buttons, and aversion to predictable form.
