But the musical, with its beguiling book by Enda Walsh, also has the team's new songs, equally strong, with hypnotic rhythms, gorgeous harmonic blends and insinuating melodies that make unexpected interval leaps seem natural and easygoing. Guy is still played with endearing slacker sweetness by Steve Kazee. Cristin Milioti remains pert and odd, with a forthrightness it would be wrong to mistake for pat adorableness.
