The time is 1959, a seedy bar in Philadelphia. The audience is about to witness one of Billie Holiday's last performances, given four months before her death. More than a dozen musical numbers — including “What a Moonlight Can Do,” “Crazy He Calls Me,” “Easy Living,” Strange Fruit,” “Taint Nobody’s Biz-ness If I Do,” and “God Bless the Child” — are interlaced with salty, often humorous, reminiscences to project a riveting portrait of the lady and her music.
