Knepper documented this tour meticulously in a series of letters he sent home to his wife, Maxine, his daughter, Robin, and his son, Timothy. These letters were recently found carefully preserved in a dusty box in the attic of the family home, and have now been transcribed by his daughter. They provide a fascinating glimpse into the inner circles of a notable piece of jazz history, and the life of a touring musician, who was also a devoted family man. He paints vivid portraits of the personal life of the musicians he worked with, and his descriptions of the Africa's landscapes and people provide a vivid portrait of an era in which there were few civil rights for Africans in their own lands. Knepper's daughter is hoping to publish these letters in the near future.
