I keep forgetting you Americans (and other foreigners) don't get all out TV, I do quite like the Randall & Hopkirk deceased remake, with the caveat that I was too young for the original, though I did like it despite not being a fan of Reeves and Mortimer.
Heh, I am old enough to *cough, wheeze
* seen the original, at least after it made its way across the pond. It was wonderfully low budget, for the scenes where the ghost suddenly appeared the whole onstage cast would freeze, the actor playing the ghost would walk on, take his position, and everone would unfreeze. The little bit of film with everyone frozen and the ghost walking on would be left on the cutting room floor.
I found it while looking for the soundtrack from the original, which might be good for use in game, and I don't think that anyone else at the table has ever seen the show, at least enough to recognize the music.
