 The fictional band for "Toe The Line", The Bunkers, was inspired by British artists such as The Beatles and Dusty Springfield who recorded German versions of their hits.Unlike the other Neumond recordings that were sung by talent in Germany and Austria, COPILOT worked with an English singer and taught him the German lyrics phonetically.In the Wolfenstein universe, English is a dying language, so COPILOT intentionally kept the singer's mispronunciations to infer that the British band was being forced to sing in a language they do not understand.
