Steven Taylor and Dodo Chaplet booked rooms at the saloon as well as one for the First Doctor when he returned from the dentist. The Clantons mistakenly believed this Doctor to be Holliday and forced Steven and Dodo to stay in sight, having them sing and play piano at gunpoint. They repeatedly performed "The Ballad of the Last Chance Saloon."
At this point, Kate returned and distracted them with her own performance. The Doctor arrived just as they finished and, through a series of misunderstandings, was taken for Holliday.
From upstairs, the real Holliday fired his gun at the ceiling and shortly after Wyatt Earp arrived and arrested the Doctor. The Clantons were still adamant that they were to kill him, so they organised a mob that met at the saloon. From there they marched on the prison.
