After taking some time out (in 1969) for more post-polio physical therapy, I plunged back into touring, and made important appearances in New York, Paris, and London. The concert in Paris was especially poignant for me. The revered Nadia Boulanger, “Mademoiselle,” came to the concert and we had an emotional reunion afterwards. She was very moved to hear me play fifteen years after I had been knocked down by polio. I had been studying with her 15 years earlier, in 1955, right before the polio struck, and she had done everything possible to help me at that time. 1970 also saw a first performance with Neville Marriner, who at that time was Music Director of the Los Angeles Chamber Orchestra.
