I have been able to read the information in Jon's link in the form of an e-mail that someone has sent to me.

The link neither confirms nor denies the story. What is important to me, as an admirer of Itzhak Perlman the human being as well as Itzhak Perlman the musican, is that true or not, it is entirely consistent with the sort of person he is. He has had my utmost respect for many years.
