I wish he were so that I could talk to him. You might try the linked in website as there are a lot of former Knoll people on it. Stewart Rosen might know. I think I also saw John Parson's name on there.
Well, good for Jack. Hope he is still playing his trumpet. I only got to meet Cathy once so I guess it is good for her too. They say "it doesn't fall very far from the tree."
