Because I'm in a Who-ing Mood

With much gratitude to CrackedCosmo at YouTube, I'm posting "The Three Doctors", a serial from the Jon Pertwee era, guest-starring Patrick Troughton and William Hartnell. Split into three parts, this is Episode One.

Part Two.

Sadly, as you see in Part Three, William Hartnell was too ill to participate beyond pre-taped segments. He passed away only a few weeks after filming was completed.
