I have been aware of this thread for some time and wish to comment on a couple of things: the woman companion referred to above would have been Secorra Gutierrez y Plarres-Montes (1945-1976), who, at the time she and LH met, was my roommate. Although her many international commitments with the UN and WHO as a nurse-practitioner placed a long-distance strain on them, these two seemed determined to make a life together. A passionate music-lover, she inspired not only his later commitment to health care but also certain strains of his music. When she died in Paris in '76 while their relationship was still young, LH seemed to lose all heart for writing and singing and dropped out of sight musically. Fortunately, after she was lost, his determination brought him to medicine, and he married, I think in '84 at the end of medical school (to another physician), raised 2 musically-accomplished children and is once again writing songs!
