Tom Baker & Lalla Ward or Louise Jameson.
SJS was OK but she wasn’t a big favorite of mine. I liked Jo Grant more.
Those Big Finish audio dramas have Tom and others in them. They are pretty good. I’ve bought a few.
I liked the old Dr. Who shows and I think Peter Davison was the last actor when I watched.
Tom Baker was the best know but there were others just as good, I really liked the series when Jon Pertwee was the Dr and he had the fellow that played the Brigadier.
