If Philosophy are responsible for Lee's departure they are lacking something in the way of common sense. His knowledge of, and enthusiasm for, the products, generated huge sales on qvc and, if you read the customer reviews, it is clear that he was well liked and respected by the viewers.
QVC should have at least mentioned him on the fifth anniversary show, if only to say that he would no longer be part of the Philosophy presentations since they must have known that his absence would be commented on.
I shall miss Lee's presence at QVC as I liked his style and only used to wish that Ali Young would shut up and let him tell us about the products without her wittering on in her inane actual fashion. Literally.
