 The title of the show ""Hi-de-Hi"" originated with Norman Bradford who claimed to have taken it from an American film; he began using this as a cheer to which the audience spontaneously responded "Ho-de-ho".Another BBC television series, "Doctor Who", featured an episode entitled "Delta and the Bannermen", which depicted an alien attack on the fictitious Shangri-La holiday camp (in reality the Butlins camp at Barry Island).As with the real camp, Shangri-La was staffed with Redcoats played by extras.
