Tonight we begin the Black Guardian Trilogy with “Mawdryn Undead” with the 5th Doctor, Peter Davidson for Friday Night Who. As always, join us on twitter for the live tweet-a-long. Just follow @vortexglenn, @vortexshaun, @VortexKeith and @travelvortex, and look for the #FridayNightWho and #MawdrynUndead hashtags. We push play at midnight, CST.
