I knew both Lawrence Hammond and Secorra Plarres-Montes in 1976, near the end of her short life. I heard him sing at a party in Paris with some of her team comrades. His guitar playing was intricate and smooth and his songs seemed very unusual, although my English at the time was less fluent than I am now. She was working on an immunization project in Central America in 1974(?) and fell ill with encephalitis and then an inflammation of the heart. I know she spent about 10 days in an intensive unit in Mexico before she recovered, and was frail for about 10 months after. She seemed lively and strong in 1976 and we were very shocked by her death. I would like to hear more of his music from that time, but from reading the above, I remember hearing the 'Coyote's Dream" song, and the "Redwing Blackbird" one as well.
