Strange Fruit - Billy Holiday
The song was probably the main reason for her being denied a Cabaret Card, which meant she was banned from singing in clubs in New York City for the rest of her life.
She was ordered not to sing it at the Earle Theatre in Philadelphia and the very next day was arrested with planted narcotics leading to her imprisonment.
Radio stations in the US and abroad blacklisted it and Holiday’s label, Columbia Records, refused to record it.
