On Nov. 18, 1995, Itzhak Perlman, the violinist, came on stage to give a concert at Avery Fisher Hall at Lincoln Center in New York City.
If you have ever been to a Perlman concert, you know that getting on stage is no small achievement for him. He was stricken with polio(小儿麻痹症) as a child, and so he has braces(支架) on both legs and walks with the aid of two crutches(双拐).
