There was an unearthly quality to the way he sang that melody that night - as if he were winging through unknown worlds in search of sources of strength beyond himself. His eyes were open, fixed, but gazing inward. There was a sweetness and sadness, a sense of pain and yearning in his voice - soft, tremulous, climbing and falling and climbing again. And when he was done there was a long silence - and in that silence I thought I heard distant cries, and I was afraid.
