Bard are known as "the Bard of Avon" (often simply "the Bard") and "the Bard of Bengal" respectively. The word is a Celtic loan word from Scottish Gaelic "bàrd", Irish "bard", Welsh "bardd". In 16th-century Scotland, it was a derogatory term for an itinerant musician; nonetheless it was later romanticised by Sir Walter Scott. In medieval Gaelic and Welsh society, a "bard" (Scottish and Irish Gaelic) or "bardd" (Welsh) was a professional poet, employed to compose eulogies for his lord (see planxty). If the employer failed to pay the proper amount, the bard would then compose a satire (c.f. "fili", "fáith").
A Town Called Mercy called the Gunslinger. However, the Gunslinger is a product of experiments by Jex to win a civil war on his planet, and the Doctor is unsure of what is the right thing to do. Showrunner Steven Moffat pitched the Wild West theme to Whithouse when thinking of ways to give each episode a distinct theme. Whithouse further developed the theme, including classic Western tropes and a sympathetic villain. "A Town Called Mercy" and the previous episode "Dinosaurs on a Spaceship" were the first to enter production for the seventh series. Much of the episode was filmed in March 2012 in
