I think I must have watched a well above average number of episodes of Crossroads. So, Kathy Staff, for me, will always be Doris Luke. She went about with an extraordinarily glum expression on her face.
Oh, did she play another character? Apparently.
Indeed, as well as donning wrinkled stockings on umpteen occasions, Kathy Staff holds the unusual honour of having been in all three of that unholy ITV trinity of Crossroads, Coronation Street and Emmerdale (when it was a 'Farm'). And she was in Open All Hours.
Quite a star really. Her appearances on This is your Life and other such programmes also showed her to be a thoroughly congenial lady off screen.
