At that early Tarrytown Fest, KLS said that it became apparent during filming of a particular episode that Hall (whom she says suffered from both nervousness and "a bit of" a drinking problem [is that like being a little pregnant?]) simply could not continue, so Karlen was hired. I'm looking forward to what Hall has to say about being replaced on the show. Wasn't it also one of KLS' recollections that he quit acting after DS?
As I mentioned some weeks ago, it's called the Woman's Club of Hollywood (formerly the Hollywood School for Girls). Usually the name Hollywood Women's Club refers to a clubhouse in Florida. Anyway, I've been to the October location-- it has a large event room, a nice lobby, extra rooms upstairs and a parking lot (!) in the back.
