Katz is perhaps best remembered for the management and production
business he and his partner Sandy Gallin ran for 15 years. Between 1970
and 1985 they created and produced ``Donny and Marie'' TV series in
addition to other series and numerous specials, including specials
featuring Mac Davis, Paul Lynde,
Dolly Parton, Cher and the Emmy winning
special ``Sold Out, '' which starred Lily Tomlin and the late Kate
Smith.
