Dear GT: tsuwm introduced us to Mrs. Byrne's book, which is now out of print, and reprint apparently delayed by her having a row with her editor. She was daughter of famous violinist Jasha Heifetz, and I think her maiden name may be on reprint when it finally appears. You can find information about it in Amazon's site.Here is a URL about it:
