Goodbye, Mango Sergeant

In the mid-1960s, Keith Walker said goodbye to the land of his birth to join his mother in England. It was the time of love and ''flower power'', but life in London for a young, black man was cold, bleak, unfriendly and presented a whole new set of challenges. Every day was a struggle in his new, adopted home, but Keith accepted his fate and decided to do the best he could. Now, nearly 50 years on, he looks back on his life, its joys, its sadness and, finally, its success.
