I found this 1982 interview with Valerie on Youtube. There are 2 parts, linked below. In Part 2, she discusses the show, which was then in its 8th season. Included: she talks about Mackenzie being back and Howard Hesseman joining.

Seen it before, but never posted it. I may or may not have thrown her Arsenio Hall appearances up here. I know I did Letterman. Hope some others watch. I'm guessing Howard Hessemen was supposed to be a big "get" for them, coming off his WKRP work.

I know I saw both her Arsenio and Letterman interviews and I know I was lead there from a post from this website so....
