If it is in fact Feinstein you are looking for, as Sylvie suggested, you can find a whole mess of sites by using his name and searching the net. There are at least 25 listings including fan-clubs and bios and references to his recordings. And if this is the guy you saw on TV, try to find a copy of his book outlining his years as Ira's assistant. It's VERY good. I'm afraid I can't remember the title as it's been several years since I read it.
