Doctor Who: The Ultimate Adventure was a musical stage play that ran from 23 March to 19 August 1989. Jon Pertwee reprised his role as the Third Doctor for the initial run, with David Banks as his understudy for a couple of performances when Pertwee fell ill. The rest of the run saw Colin Baker take over as the Sixth Doctor.
The Daleks and the Cybermen form an alliance to kidnap the American Envoy and ruin a peace conference on Earth. The Doctor meets a new companion, a Frenchman called Jason. After they fail to stop the Cybermen taking the US Envoy from a nightclub, they are joined by a singer named Crystal who works there. After a trip to Altair Three and then the Bar Galactica, they meet Madame Delilah but are forced to flee along with a small furry creature called Zog.
The travellers are captured briefly by the Daleks. They navigate the ship through an asteroid field before making a series of short trips, then confront the Dalek Emperor. The Doctor tricks the Emperor into revealing that the Daleks intend to betray the Cybermen and a battle breaks out between the two. Returning to Earth, the Doctor realises the US Envoy is under Dalek influence and programmed to destroy London with a Dalekanium bomb. The Doctor breaks his conditioning and defuses the bomb by putting it in a teapot.
