Video - Two Doctors (how could you forget that?)
Audio - the Four Doctors
I didn't forget the Two Doctors, I mistakenly dismissed it thinking it couldn't be an Anniversary, thinking that was too little time between 5 Doctors and Silver Nemesis
(Runs off to look up dates)
ETA: The Five Doctors Nov 23, 1983; The Two Doctors Feb 1985 - So how is The Two Doctors an Anniversary Special?
I'll have to be sure I have The Four Doctors Audio prior to 50th Anniversary
One Day I hope to be the Man my Cat thinks I am
Where are we going? And why are we in this Handbasket?
