On this day in 1965 you could be forgiven for thinking that BBC cut-backs had forced William Hartnell to play multiple characters in Doctor Who, specifically having to double up as the Doctor and the Daleks for The Space Museum! Of course it was just a clever ruse, but episode one of this series did draw a huge audience of 10.5 million viewers, so maybe they were on to something!
Two regenerations and 6 years later, the Third Doctor faced episode three of Colony in Space. Broadcast Saturday April 24th 1971 at 6:13pm and watched by 9.5 million viewers. Then, on this day in 2010, 8.59 million viewers didn't dare blink during the Eleventh Doctor adventure The Time of the Angels.
On this day in 1964 part three of The Keys of Marinus (titled The Screaming Jungle) was broadcast at 5.29pm and watched by a 9.9 million viewers. Also on this day, in 1970 episode 6 of The Ambassadors of Death was watched by 6.9 million.
We start this day back in 1969 with the epic Second Doctor swansong, The War Games. Episode Two was broadcast at 5:14pm that Saturday tea-time, and watched by 6.3 million viewers. From a mop-top to all teeth & curls, and part two of the Fourth Doctor adventure Revenge of the Cybermen which was broadcast on this day in 1975 to an appreciative audience of 8.3 million. Finally for this day, it's a 33 year jump to new-Who and the first part of the Tenth Doctor's encounter with the Sontarans - The Sontaran Stratagem was broadcast in 2008 at 6:19pm, and watched by 7.06 million viewers.

Russell T Davis, the man who steered the good ship Who out of the "wilderness years" and back to our screens, was born on this day in 1963. April 27th is also Jenna Coleman's birthday.
