Do not go gentle into that good night

"Do not go gentle into that good night" was a poem published by Dylan Thomas in the 1950s. The Eighth Doctor read some of it to Liv Chenka and Helen Sinclair aboard a Gallifreyan escape shuttle and told them that it was about not giving up in the face of death. (AUDIO: Ship in a Bottle) A smirking Clara Oswald quoted the titular verse when she caught wind of the Twelfth Doctor's "pre-mortem party" in Medieval England. (TV: The Magician's Apprentice)
