I've begun reading a book by "another" Ivan, Ivan Vaughn. The title is "Ivan: Living With Parkinson's Disease," published 1986 by Farrar Straus Giroux. Vaughn, a childhood friend of John Lennon who shared his diagnosis with John shortly before Lennon was killed, is a young onset pwp and at least was a lecturer in Cambridge, England. I'm not far into the book, but wondered--does anyone know whether Ivan Vaughn has been on this list, or what's become of him? Regards, Rick Hermann
