3. It's Blood-Soaked History! Let's Sing!
In the early days Doctor Who could get away with pretty much anything. Indeed, as mentioned above, that was sort of what the program was
for. And so, When Donald Cotton wrote up the tragic affair of the O.K. Corral, it probably seemed perfectly reasonable that we should build up to the carnage with a jaunty showtune. The Ballad of the Last Chance Saloon, if you are unfamiliar with it. Lynda Baron sang the tune, both within the drama as busty prostitute Kate (Oh sure, they never flat out said so, but come on...) and also as a meta-narrator, providing new verses between scenes updating us on the action. Which was probably not entirely necessary as we'd just seen the action, but still, as framing devices go it was fine. Where things start to go slightly off the rails is when Steven and Dodo are mistaken for traveling performers and forced at gunpoint to sing the same song. And they know it. Either Steven and Dodo are both amazingly talented sight-reading pianists, or Innes Lloyd had already decided he didn't care for the job and was just seeing how far he had to push things before someone called him on it. Pretty far, it turns out.
