Lynn Ahrens and Stephen Flaherty have created scores for a host of musicals and films, earning a Tony Award, two Oscar nominations (for the animated film Anastasia), and a slew of other honors along the way. Right now, however, the ever-busy pair are preparing for new productions of two of their biggest hits, Once on This Island, which will play New Jersey’s Paper Mill’s Playhouse, May 30-June 24, and Ragtime, which will play London’s Open Air Theatre, May 18-August 8, as well as creating a musical version of the hit film Rocky.
